Do you know the reasons for side grinding, falling pieces and breakage of point rails and the improvement methods?

Rail Infrastructure

Do you know the reasons for side grinding, falling pieces and breakage of point rails and the improvement methods? The reason: ①The switch position is incorrectly laid; ② The basic rail moves laterally and three seams appear (there are seams between the basic rail and the sliding table) There is a gap between the lower jaw of the basic rail head and the upper part of the rail bottom and the contact part with the rail support, and there is a gap between the tail of the rail support and the shoulder of the slide plate); ③The basic rail functions to fatten the edge; ④The bending size of the basic rail is incorrect; ⑤The hanging board and sleepers in the switch part failed; ⑥The top iron of the pointed rail is out of joint; ⑦The sliding bed plate boss is worn; ⑧The large connector is poorly connected. Possible remedial measures: ① Use a high-precision theodolite to measure the direction of the entire fork area and the 100 m before and after the line, and adjust the entire fork area and the 100 m before and after the line based on the measurement results. ② Replace failed sleepers in a timely manner, especially the switch part, tip rail tip and tip rail heel end sleepers, and strengthen the level of the above parts and the adjustment of the hanging board to keep them at the same level. ③Tighten the rail support bolts, anchor bolts and threaded spikes. ④ Eliminate three seams and make the wooden sleepers, sliding bed boards, rail supports and basic rails tightly connected. ⑤ Install reinforcing pads on the outside of the two basic rails. ⑥At the tip of the point rail, in the middle of the point rail, and after the point rail of the two straight basic rails, install Install one insulated gauge rod with lengths of 1800 mm, 1400 mm and 1200 mm to stabilize the switch part frame. ⑦ Timely grind the active side fat edge of the basic rail and the non-active side fat edge of the tip rail. ⑧The separation of the top iron from the seam is closely related to the crawling of the tip rail. When the top iron is not in close contact, it will cause uneven stress on the tip rail, false gauge and hard bending of the tip rail. While correcting the crawling of the tip rail, pad the top iron so that the static gap between it and the basic rail is no more than 2 mm. ⑨ The wear of the sliding bed plate will cause the switch to be blocked, the switch to have no indication, the hanging plate and the tip rail to be loose, and the operation to be difficult. A large number of sliding bed plates are worn at the duplex switch site, and the entire sliding bed plate should be replaced during maintenance and repair operations. The 1#, 2#, 3#, and 4# sliding bed plates in front of the switch rail must be cut into oblique sliding bed plates on site to meet the electrical insulation requirements before they can be installed.

Do you know the causes and effects of fat edges on rails?

Rail Infrastructure

Do you know the causes and effects of fat edges on rails? ◆Causes 1. The track is too rigid, and irregularities on the track cause huge power to the wheels; 2. There is a large difference in vehicle speed through the curve, resulting in eccentric load on the inner and outer rails, or due to improper super-elevation settings; 3. Sliding of wheels; 4. The steel is of poor quality. ◆Inspection method 1. Visually inspect and use a ruler or depth gauge to measure, 2. Use a profilometer to measure. ◆Development results 1. After the fat edge is generated, if it is not repaired in time, it will affect the train operation. 2. Affects track status inspection, including manual static inspection and track inspection vehicle dynamic inspection for track gauge measurement. 3. The fat edge of the rail end of the ordinary joint will affect the rail seam setting effect and cause blind seams; the fat edge of the insulating joint will cause the insulated rail end to be extruded and cracked. Severe fat edge will cause the insulating joint to be connected and the insulation will fail, resulting in Red light band. 4. The sharp edge produced by the point rail will cause the point rail and the basic rail to not be in close contact, causing the switch to fail. When the train passes, the extrusion causes the fat edge between the point rail and the basic rail, which may cause pieces of the point rail to fall off. ◆Repair method 1. When the fat edge is larger than 0.3mm, it needs to be repaired. The fat edge of the rail can be processed by grinding (or milling). 2. For fat edges caused by superelevation setting of the curve, the curve parameters should be optimized while grinding rails. It is advisable to adjust the superelevation settings before grinding the rails. 3. Rails that exceed the service limit should be replaced. ◆Preventive Action 1. Select high-strength grade rails that match the operating conditions to avoid or reduce the wheel-rail contact pressure stress exceeding the rail yield strength value, which can reduce the occurrence of fat edges. 2. Set the curve super height reasonably to prevent the lower rail from bearing excessive wheel-rail contact compressive stress load. 3. Improve the smoothness of the joint position, improve the elastic foundation under the joint rail, and reduce the impact load when the wheel passes the joint. 4. Periodically polish the rails and joints, repair the rail profile in a timely manner, and optimize and improve the wheel-rail contact relationship. 5. To prevent the fat edge of point rail, the top surface of point rail and the basic rail can be chamfered before the point rail is put on the road. When replacing the tip rail, try to replace the basic rail simultaneously; if it cannot be replaced simultaneously, it is necessary to measure and adjust the reduction value of the tip rail after replacement to avoid premature stress on the tip rail.

What's the reason of the train doesn't derail?

Rail Infrastructure

As a unique means of transportation, the biggest difference between trains and other land vehicles is probably the part in contact with the ground. Cars mainly use rubber, a material with high friction and elasticity, to make tires, but trains cannot be made with wheels. They also need the cooperation of rails to operate normally. But we can see that the wheels of the train press forward on the thin rails, but there are very few derailment accidents. Why is this? The wheel of a train looks like a cylinder on the outside with a slightly larger "disc" on the inside. Many people think that the disc on the inside is what fixes the wheels and rails. In fact, this is not the case at all. After all, if part of the disc contacts the rails for a long time, the friction will inevitably increase significantly and affect the speed of the train. Therefore, the existence of this disk can be said to be an "insurance", which can only play its role in critical moments. The key is that the "cylinder" on the outside is actually a cone, or a truncated cone to be precise. A simple cylinder will obviously not be able to keep moving in parallel on a smooth rail surface, but if there is an inclined surface, it will be different. Even when turning, the balance of the tires on both sides can be maintained. So on the surface it seems that the connection between the train and the rails is not close, but in fact the train stays on the rails in a very stable manner. Furthermore, the weight of the train itself has reached a certain level, so it will not be unstable because it is too light, and of course it will not be unable to speed up because it is too heavy. Therefore, the train track may seem to have a simple structure, but in fact it contains many mechanical principles to ensure that the train does not derail. "Learning" on the Rails In addition to the train itself, the rails of the train are obviously also an extremely important part of transportation. Without suitable rails, the train will be unable to move. We know that in addition to the two basic rails, sleepers and ballast are also indispensable parts of railway tracks. The sleeper has many functions. It plays the role of connecting two rails, dispersing the huge pressure of the train pressing on the rails and transmitting it to the roadbed below. Because the sleepers will deform to a certain extent when the train passes by, the material of the sleepers needs to be both soft and tough. As for the role of ballast, it is mainly to buffer the pressure received by the sleepers and increase the life of the track. In addition, the drainage function provided by the gravel is also very important, which can allow rainwater to be discharged in time without greatly reducing the friction between the wheels and the track, thus increasing the safety of train driving and ensuring that it can operate under various climatic conditions,safety.

Advance Transportation

General

T ransportation is the most important aspect to know if you want to know the railway system very closely. 90% of railway employee and rail users have to gain a minimum knowledge about transportation, in whichever department they have been. Especially those who are from Operating and Commercial background, must have a core knowledge of it. Transportation have two parts i.e. 1. General Transportation, which are taught in all ZRTI for initial students and 2. Advance Transportation, an advance course for all traffic probationary taught in IRITM, Lucknow. In this topic, will going to draw an outline about advance transportation and discuss why all the students who are pursuing Rail Transport Management course, should gather knowledge about it. Transport Management is about a study of seeking vast knowledge about Railway's operational activities, commercial activities as well as traffic accountable activities. Advance Transportation covers the advance aspects of railway operation and analysis of day to day operating performance by applying numerous number of formulae and statistics.  Here are some below mentioned consideration of Advance Transportation and its outcome for learner:-  Freight train operations It is said that 65% of railway revenue are generated by selling goods service. Knowledge of freight train operations considered as a primary gateway to advance studies. It includes some essential points and indicates that can help the seekers to get a clear concept about freight business:- Knowledge of Transportation products offered by Railways to their customer Knowledge of the variety of commodities to be moved, with different characteristics & type of wagons required Knowledge of commodity rates enlisted by Indian Railway Conference Association(I.R.C.A)  Knowledge of Preferential Traffic Schedule and Rationalization Scheme published by Rail board in every year from 1st April under Railway Act. 1989 Knowledge of The activities of 8 core industries included Coal, Crude oil, Natural Gas, Petroleum refinery products, Fertilizer, Cement, Steel and Electricity generation and their relation with Indian Railways  Knowledge of Port Railway Management. Indian Railways gave Rail Transport Clearance(RTC) to all ports that they may build Private Port Terminal(PPT) with some policies generated by Rail board to ease the dock railway operation Knowledge of Container Rail operations, Container Rail Operators and their various policies, Container Class Rate(CCR) in which containers are charged to transport Knowledge of Various Running and Non Running Freight charges including Busy Season Charges, Hauling Charges, Wharfage, Demurrage, Punitive Charges, Congestion Charges etc.  Knowledge of various Freight Incentive Schemes published by Rail board to boost the freight marketing Knowledge of pattern and fluctuations in demand for rakes/wagons due to changes in the level of production, Seasonal variation of demand, pattern of Rake Allocation System in Indian Railways The Control Organization - The Nerve Centre of Railway system: As an organization develops and becomes more complex, the need for coordination between its various units becomes more urgent. The Control organization is one of the principal means by which this essential coordination is obtained in railway operation. Position of the Control officer in the railway organization can be compared with that of the brain in human body. Just like the brain, it guides all operations on the railway. The very skill of Coordination, Communication and Leadership can be seek out from this centralized organization.  C oaching train Operations  To operate coaching train, may not bring huge revenue to railway like goods train but we have to understood that operation of coaching train is a primary and fundamental duty of railway to society. Lots of advance consideration, theories, methods are included in this operation:- Various type of Coaching services served by Indian Railways to nation i.e. Suburban Service, Passenger Service, Mail/Express Service, Premium Service, Parcel Service, Railway Mail Service. Types and Characteristics of various Passenger Coaching Vehicles(PCV) and various Other Coaching Vehicle(OCV). Works and Activities of Passenger Profile Management(PPM).  Robust approaches of creating locomotive link for coaching train to ensure that no link would not be impacted due to failure of other link in the whole loco cycle.  Mathematical way of creating rake link in such manner that stabling time of any rake should be minimized and also to run more trains using less number rakes. Different approach of 'Punctuality' study including punctuality calculation formula, close study about factors which are affecting punctuality of passenger train.  Approach of creating Railway timetable and augmenting capacity utilization  It deals with some principles of timetabling and defines some notions of “good” quality of a timetable with respect to various stakeholders involved in a railway network (including passengers as end-users, freight customers and the network operator). This is followed by an elaboration on various parameters and how they affect the quality of a timetable.  Principles of rail-traffic timetabling.  Current timetable observations on some section. Capacity utilization of sections handling mixed traffic. Analysis of how various parameters affect congestion.  Junction congestion analysis. Recommendations for improvement in capacity. Distribution of slacks and allowances are made. Interchange management Ministry of Railway have 18 open railway zone, inter-connected by each other and each of them is a business module. Each railway owned a sufficient number of Rolling stock which are considered to be the most worthy assets as a transporter. If we consider the whole railway network as a business, then all the zones are considered to be investor. They used to invest their stock to play among the network. Their stocks juggled among the 18 zones by different interchange or Junction points. Any of the railway can use other's stocks for operational purpose. A fix amount of 'Hire Charges' are levied on debtor railways will be divided by among creditor railways in the proportion of their credits. Here the amount of credit depends on two figure, 1. Figure of Interchange Balance of a railway and 2. Figure of Wagon Balance of a railway. Proper and vivid way of interchange management helps to maintain a well balanced inter-railway financial adjustments. Beside wagon interchange, Coach interchange and loco interchange are also hire charged as per different rates.  Modernization and latest developments in Railway transportation Modernization means to modernize Railway to meet the challenges of economic growth, cater to the aspirations of common man, the needs of changing technology while ensuring at the same time socio economic requirements of the country. It includes Modernisation track, Strengthening bridges, Eliminating all Level crossings, Automatic signaling on busy routes, GSM based mobile train control system, Introduction of new generation motive power, Introduction high speed LHB coaches, Introduction of high haul freight wagon, Modernisation of major stations, Development of multi modal logistic parks, To set up real time information system, Attracting private investment through PP models for freight terminals, high speed railway lines, leasing wagons, coach and loco manufacturing renewable energy generation etc, Dedicated freight corridors, High speed trains, Increment of Avg. Speed of Goods train, Offering Graduate programme in Railway Technology about Advance Transportation. Various operating statistics and ratios  Advance Transportation are enriched with various operating statistics and ratios which are helps railways to express their service performance through mathematical calculation. TRAFFIC STATISTICS - included with Wagon loading, Wagon mobility Wagon Turn Round days, Wagon usage, Productive and Unproductive Service statistics, Wagon detaintion, Marshaling yard statistics, Terminal statistics. POWER STATISTICS - included with Engine usage, Engine demand, Engine utilisation, Fuel and Energy consumption, Engine failure statistics. ROLLING STOCK STATISTICS - included with Rolling stock holding and availability and Repair & Maintenance statistics.  Significance of Information Technology in Railway transportation system Think about this, within Indian Railways there are at least trains are running on daily basis, that means in each hour signals are being followed, points are being crossed over. Now imagine how stressful that operation would have been if it was ran by human. The system has to be up and running 24x7, with almost 0 tolerance and 0 lost time. We would have to have thousands if not million exceptionally skillful people to do this things day in and day out. And that's where the magic of Information Technology comes to play. The extensive use of IT systems increases the operability multiple fold, brings a transparent data of daily traffic activities and exposed as daily basis MIS report to stakeholders. In account of transportation lots of IT system are there:- Freight Operation Information System(FOIS):- For handling Operational and Commercial aspect of Goods traffic of Indian Railways Coaching Operation Information System(COIS):- Operational aspect of Coaching traffic  Punctuality Analysis and Monitoring Module(PAM):- Data collection of punctuality loss and analysis them Integrated Passenger Information System(IPIS):- A Integrated module of public addressing with proper running status of passenger trains Terminal Pipeline Management System(TPMS):- IT based prediction of terminal congestion of a particular freight terminal Station in accordance with pipeline flow, rake handling capacity over there. Time Table Module:- App based Time Table making modules of Indian Railways. Planning and Infrastructure (Traffic)  Whenever railway has intend to introduce a new traffic at their network, the consideration will be that, if there is a proper infrastructure to operate this train. The main objective of this, is to define the processes of managing the capacity of railway infrastructure with the aim of achieving high-quality operative management of traffic due to the efficiency of transport flow on the infrastructure. There are two ways of achieving high-quality, hassle-free traffic management, one is (i) By incurring expenditure and another is (ii) Without incurring expenditure. First one includes some important consideration like, increasing loading/unloading potential of the terminals to least the terminal detention, building long loop on long and heavy haul train operated sections, provision of shunting neck to all yard to ease the yard shunting without blocking mainline, provision of direct crossover in big junction station, auto signaling on congested section, provision of Bulb line to avoid train reversal, sufficient development in railway goods shed siding for rail users etc. Now, the planning without incurring expenditure be like efficient planning to augment section capacity, giving priority as per schedule, right powering of trains, maximizing long haul train, sufficient crew balancing at junction point with adjacent division, proper planning by board controllers etc.

PM Gatishakti - Development within Indian Railways and with others mode

Planning

I n 2021 the GOI launched a ambitious master plan named  GatiShakti  scheme for multi-modal connectivity plan, with the aim of coordinated planning and execution of infrastructure projects to bring down logistics costs. Ensuring integrated planning and implementation of infrastructure projects in the next four years, with focus on expediting works on the ground, saving costs. Besides cutting logistics costs, the scheme is also aimed at increasing cargo handling capacity and reducing the turnaround time at ports, railway terminals to boost trade.  So while I'm talking about railways, few questions may be arise, what kinds of Gati Shakti needs in railway system to boost up cargo handling capacity more faster? Can a single boost up will changes railway cargo handling nature? While GOI launched 'PM GatiShakti' scheme, Indian Railways framed a schemes named GatiShakti Cargo Terminal(GCT) scheme under PM GatiShakti scheme, in order to boosting up terminal development, there rake handling capacity of newly constructed or existing private sidings and private freight terminals. Hope lots of siding owners will be interested to invest on this latest scheme. GCT scheme is the very first initiative taken by Indian Railways to boost up multi modal connectivity under PM GatiShakti. But is this single initiative be sufficient enough for bringing Gati & Shakti in freight operation? Various innovative ideas can be thought-out from railway side under PM GatiShakti. Development of railways owned terminal Development of railways owned terminal under PM GatiShakti besides GCT scheme can be done positively. It's very urgent and also essential to invest on development of railways owned goods shed/siding under GatiShakti scheme apart from GatiShakti Multimodal Cargo Terminal (GCT).  Upgrading half rake terminals to full rake capacity to avoid multiple placement. Sufficient loading-Unloading lines to decongest terminal pipeline. Upgrading all 6-10 hrs. working terminal to round the clock working hours for quick procurement. Installation of mechanized loading-Unloading facility for covered wagon to avoid terminal detention. Few days ago, Krishnapattanam Port of AP&SEZ breaks their own record by handling a 42 BCN rake in just 3 hours 35 minutes. If they can did, why IR can’t?  Proper and hygienic warehouse facilities and Proper roadways connectivity to connect those goods shed quickly.  Universalization of container traffic in railway goods shed There was nothing more convenient than containerization of railway goods traffic. While all CTOs are used to handle their rakes from their own land, the placement policy of domestic container train in railways owned terminal should be universalized for bagged goods subjected to sufficient stacking infrastructure and mechanized system of container handling. Universalization happened only then when procedures will be simplified, rating system will be transparent and single window clearance will attract road traffic to rail. Small goods shed should be cargo aggregating point and major terminals should be cargo segregating point. The vehicle service between small goods shed and big terminals can be introduced to pick up cargo to major terminals.  Proper yard layout for quick turn round Proper yard layout for quick placement and removal of rakes. In modern era, most efficient yard structure is bulb structure, which are used to construct at all major ports in india. The construction of a bulb line enables engines to reverse without changing the direction of the train, thus reducing halting time.  Railway-IWT integration Connecting Inland Waterway Terminals to Railway. These improvement can bring a better gear up for freight operations. In a current study, an attempt has been made to link major Inland Waterways to Railways. For an example, IWAI has plannned to made up IWT at Durgachak, West Bengal and linked that with Rail. Estimated results suggest that water ways in India have a comparative advantage over the rail in terms of capital costs is much lower in case of IWT as compared to Railways. However, IWT has no comparative advantage in operation. Estimates indicate that operation and maintenance cost of railways with electric traction is minimum than transportation through Inland Waterways. In this topic i'm not actually trying to compare which is best, how to snatch modal share from rail to to IW or IW to rail. The vision of GatiShakti is to provide integrated and seamless connectivity for movement of people, goods and services from one mode of transport to another. If Railways and Inland Waterways can integrated then, Beside bulky commodities, Cold Chain Transportation can be boost up through close integration of IW River Terminal and Railway. My native state West Bengal produces a lot fishs and Crabes from Sundarban area which are treated as hinterland, is not well-connected networks of railways. No Railway goods siding or Private Freight Terminal has been made up there. This area are falls under the jurisdiction of Eastern Railway, Sealdah south suburban section, congested with passenger traffic causes inadequate scope to operate goods traffic. There was only one NH to and from Sundarban Fish Harbour is NH 117 which is passed through South 24 Parganas and end congested Kolkata urban networks. Such inefficiencies and a lack of transport connectivity adversely affect the state’s economy, increase congestion in road and contribute to post-harvest losses of temperature-sensitive goods. Waterways have the potential to support a multi-modal cold chain transportation network with reduced emissions, environmental impact, fuel usage and costs. West Bengal is the 2nd largest producer of Inland and Marine fish and such temperature sensitive goods are transported across all over India from the state. If there was a Rail connected IWT situated some where in Howrah district over NW 1 i.e. Ganga-Bhagirathi-Hoogly river system then Fishery commodity from Gosaba, the largest Fish Port of Surdarban can easily be transported via delta waterways to NW 1. Rail connectivity can also be established with South Eastern Railway within that IWT.

Rake Allocation System of Indian Railways

General

The first step in the reliability and accountability of the railway authorities with the consumers in the transportation of goods is an improved rake distribution process, which despite a lot of heavy criticism and dirty politics in the country, I personally believe that the modern distribution process has been able to make this step very much corruption free. I think It is the right of a consumer to expect a transparent and certainly regular distribution arrangement from the Railways, in return for paying service charges to the Railways. So this Rake distribution system is a huge chapter of Rails and very complex too. Allocation  i.e. distribution of empty goods for rake loading as per customer demand. Since passenger coaches have nothing to do with Rake Allocation System (RAS), we are not going in that direction. System  i.e. the way in which all the empty rakes are distributed among the customers and brought to the pre-planned stations for loading. This time the question may come to our mind, exactly  how this entire distribution system is   done?  Generally, this entire rake distribution process is done by calculating the  Oldest Day of Regulation (O-D-R)  or the oldest day of regulation based on the date and time of the form or indent received by the customer. The process can be simply said, under the same Priority, the customer who will submit the form first, the railway will have to distribute the rake first by receiving his form. Priority In case of rake distribution, this single word carries two meanings, 1. In case of coal transportation, the purpose for which the coal is to be used, ie for power generation in thermal power plants (ELC), for pesticide production plants (FTZ), for steel plants (STL) etc. 2.  Preferential Traffic Order(PTO)  issued by the Railway Board to mean the preferential arrangement of traffic. We know that a total of 8 fields in the country are divided into Core and Non-Core. They are coal, steel, pesticides, cement, crude oil, refinery solvent and electricity. Except these fields all other fields are considered as Others in railway parlance. According to PTO there are total 4 classes of traffic, A, B, C and D. All military traffic in the country is treated as A, as we all know how close the relationship between Indian Army and Indian Railways is. All traffic is treated as B on a temporary basis. All traffic under Core Industry belongs to C Class and Non-Core Industry and Others all traffic belongs to D Class, most of which class is subject to "Capturing new stream of traffic" as the main goal of modern goods transport management. Railways mainly divide their customers into these categories. > Liberalize Wagon Investor(LWI) > General Purpose Wagon Investor (GPWI) > Core customer > Others D priority and Non-Core customers > Military > Various Railways In all these parts, various government-owned and private institutions of the country have chosen the country's railway system for transporting their goods. Methodology Let's come to this time, what arrangements are made by Indian Railways to distribute rakes among all the above categories of customers? I am starting with the end of Wagon Investor customers, Core, Non Core and Others customers. But before that, you need to know, how many different places are rake loading in the country? Rake loading is done from a total of 7 locations, 1. Goods Shed Siding (GSS) 2. Container Rail Terminal (CRT) 3. Private Siding 4. Assistance Siding 5. Brownfield Private Freight Terminal and 6. Greenfield Private Freight Terminal. So, considering the different indent accepting capacity and rake loading capacity of each siding in terms of day and month, it is recommended to distribute rake as a percentage of each month in Core, Non-Core and Others category. But from where the loading is done under only one category, there is no need to distribute the percentage of rake in different categories, there is usually distribution of rake by ODR method. Again in some cases this ODR method is observed direction wise. For that, the form (Indent) must be of Non-Core category and the traffic must be more than a certain kilometer. As a hypothetical example of this, South Eastern Railway's Haldia port via ECR-bound via Dankuni, ECoR-bound, ER-bound indent will prevail in that order. Allocations made to Wagon Investor Lets come to the context of distribution and loading of private category rakes under these two schemes GPWIS and LWIS. In this case also ODR procedure is followed. These rakes will remain stable on their sidings until the owner issues a form for their transportation to the railways. The rakes will reach the loading point only through the route issued by the Railway Board after the railway authorities accept their form. Needless to say, the dominance of private rakes never matches the dominance of rakes under Indian Railways, two different perspectives. Rake distribution to military and Departmental traffic The rake distribution of military traffic is the first row dominant and vice versa the rake distribution of departmental traffic of various railways is the last row dominant. Stone rake allocation for Bangladesh Railway  For movement of stone rake to Bangladesh from different policy decisions have been formulated for increase in loading from Eastern Railway. Such allocation are done in two different ways.   A.   Except Out of Turn Quota  i.e a loading station wise cyclical quota. Suppose a zone have 10 stone loading station, allocation of rake will be made up on these 10 station, serial wise in rotational way B.   Out of Turn Quota i.e. a special priority quota given to all quoted consignor-consignee listed by Rail board based on their turnover. They are given a particular no. of rake to load on monthly basis from any nominated station.

Why we say the rail wear gauge is significant importance in rail maintenance?

Rail Infrastructure

1) Safety: Rail wear gauges help ensure the safety of train operations. By measuring the wear of the railhead, maintenance personnel can identify areas where the rail may have worn beyond acceptable limits. Excessive rail wear can lead to reduced track stability, increased risk of derailments, and compromised train operations. Regular use of rail wear gauges allows maintenance teams to identify worn sections promptly and take appropriate action to maintain safe track conditions. 2) Maintenance Planning: Rail wear gauges play a crucial role in maintenance planning. By accurately measuring the wear of the railhead, maintenance teams can determine the remaining lifespan of the rail before replacement or major repairs are necessary. This information enables them to schedule maintenance activities proactively, minimizing disruptions to train services and optimizing maintenance resources. 3) Cost Efficiency: Rail wear gauges contribute to cost-effective rail maintenance. By monitoring rail wear regularly, maintenance teams can identify sections that require corrective actions, such as grinding or milling, to restore the desired rail profile. Targeted maintenance based on wear measurements allows for efficient utilization of resources, reducing unnecessary maintenance interventions and optimizing the rail's service life. 4) Track Performance: Rail wear gauges provide valuable insights into the performance of the track. By analyzing wear patterns across the rail network, maintenance teams can identify areas of accelerated wear, which may be indicative of underlying issues such as misalignment, excessive loading, or substandard maintenance practices. This information helps in identifying root causes and implementing corrective measures to improve track performance and longevity. 5) Regulatory Compliance: Rail wear gauges are essential for compliance with regulatory standards and requirements. Rail networks are subject to specific wear limits and profiles mandated by regulatory bodies. By using rail wear gauges, maintenance teams can ensure that the railhead wear remains within acceptable limits, complying with the prescribed standards and minimizing the risk of non-compliance penalties.

human factor guidelines (Providing a great comfort) for locomotives in American rail roads

Safety and RAMS

Today i was travlling from LA and i wonder What are human factor guidelines (Providing a great comfort) for locomotives in American rail roads? and following are my observation please comment your observations below  -  1. Comfort: The term "comfortable" is arbitrary and susceptible to individual interpretation. Effective seat design and evaluation are difficult without a set of precise criteria that define what constitutes comfort. 2. Insufficient Design: Inconsistent implementation across different seats or even different trains is possible in the absence of precise requirements. Due to varying expectations and preferences, some passengers may find a particular seat to be comfortable while others may find it to be unpleasant. 3. Customer Dissatisfaction: Since comfort is subjective, passengers may have varying expectations. If the seats do not meet their personal comfort preferences, passengers may experience discomfort, leading to dissatisfaction with the overall train experience. This can impact customer loyalty, perception of quality, and even influence their decision to choose alternative transportation options. 4. Cost Increase: Unclear requirements can lead to increased costs during the design and development process. Without clear criteria, designers may need to go through multiple iterations or guesswork to meet the undefined comfort standard. This can result in additional design revisions, rework, or even the need for costly modifications after the seats have been produced. 5. Safety Concerns: Although it is not directly related to the comfort requirement. For instance, if comfort is prioritized over safety features like proper lumbar support or seatbelt effectiveness, it can compromise passenger safety in the event of sudden stops or accidents.  To mitigate these adverse consequences, it is important to establish more specific and measurable requirements. For example, specifying factors like seat cushion material, adjustable features, ergonomic support, maximum pressure points, vibration reduction, or specific measurements for seat dimensions can help improve the overall design and ensure passenger comfort is objectively addressed.   The given requirement is an arbitrary condition without particular measurements. It does not specify what is meant by "comfortable" in terms of the passenger seats. When designing and evaluating a product, this flaw may cause ambiguity and subjectivity. Unfavourable effect brought on by this deficit: Inconsistent design: - Lacking a precise and quantifiable description, different designers or manufacturers may have varying interpretations of the criteria. As a result, different seat designs might be used across the system. Users dissatisfaction: - It is difficult to ensure that the chairs match passengers' expectations and ergonomic needs because the criterion does not provide any quantifiable criteria. Increased risk of passenger's health issue: - Lack of precise comfort standards can result in chairs that don't support people well enough, causing bad posture and more pressure spots for passengers. Inconvenient seating for extended periods of time can aggravate musculoskeletal issues such back pain, neck strain, and joint pain.

Why do regular ballast bed tamping work insist on small tamping machine?

Rail Infrastructure

Regular ballast bed tamping work often involves manual labor for several reasons: Flexibility and Adaptability: Manual work allows the tamping crew to assess the condition of the ballast bed and make real-time adjustments based on their expertise. They can identify specific areas that require additional or less compaction and adjust the intensity and direction of the tamper accordingly. Manual work enables the crew to adapt to varying conditions, such as changes in the ballast quality or track geometry. Precision and Control: Manual tamping provides a higher level of precision and control compared to automated or mechanical methods. Experienced workers can apply the right amount of force and distribute it evenly, ensuring proper compaction of the ballast bed. They can also detect any irregularities, such as soft spots or voids, and address them promptly. Safety Considerations: Manual tamping allows workers to visually inspect the ballast bed and identify any potential safety hazards, such as loose fastenings, damaged sleepers, or track misalignments. These issues can be addressed immediately, reducing the risk of accidents or derailments. Manual work also enables workers to maintain a safe distance from moving trains and machinery, ensuring their safety during the tamping process.
