For the engineers of Delhi Metro, bringing the Airport Express Link's operational speed up to 100 KMPH posed a significant engineering task.
The key accomplishments of this enormous endeavour included careful planning, 24-hour supervision, and a determination to avoid having the work interfere with passenger operations.

One of the most difficult technological developments in the country's annals of Metro train operations will be this. 

The goal was only reached within six months, far ahead of the anticipated deadlines, thanks to a detailed mechanism for the replacement of some rail components,
maintenance and repair of civil structures, and re-profiling of some Rolling stock components.

The increase in operational speed required numerous track-related maintenance tasks to ensure that passengers would experience the least amount of inconvenience possible,
making it a historic technical development in Metro train operations. 

In order to make them more compatible with the revised speed strength, the main activity included replacing more than 2.6 lakh existing tension clamps on the rails throughout the complete AEL network with high-frequency tension clamps.
