Purpose for Upgradation of system and virtual Signal Implementation

In between the train stations, there are interlocking points where the train changes tracks, in case of any signal glitch at any point, the entire section between two interlocking stations is affected, and train moves at a restricted speed. The virtual signal system allows train to run at a normal speed, except for 500 meters from the location of glitch.

DMRC initiated the process of signaling up-gradation with purpose to identify glitches and upgrade systems as per requirement so that affected trains still run at regular speeds of 33-37 Km per hour. The up-gradation provides smooth operations of train and prevent stations from overcrowding.
