Nearly 15,000 commuters —mostly office goers—suffered as the Delhi Metro Rail Corporation (DMRC) was forced to cancel 10 round trips between 10 am and 4 pm on Lines 3 (Dwarka-Noida) and 4 (Dwarka-Anand Vihar).

For users of the Delhi Metro, Tuesday turned out to be a day of delay. A technical snag in the the Metro’s communication network threw everything off track.

Nearly 15,000 commuters —mostly office goers—suffered as the Delhi Metro Rail Corporation (DMRC) was forced to cancel 10 round trips between 10 am and 4 pm on Lines 3 (Dwarka-Noida) and 4 (Dwarka-Anand Vihar).

The problem started at Rajeev Chowk when a train suddenly stopped near it due to the failure of the Automatic Train Supervision (ATS) server, said DMRC officials.

The problem started when the display boards on trains on these two routes went offline. These display boards, installed at the front and back of each train, flash the unique ID number assigned to each train.

“The ID numbers of the trains went off due to a technical snag in the ATS system. As a result, the centralised Operational Control Centre (OCC), that remotely controls the movement of trains couldn’t monitor and operate the trains. This led to suspension of the service on Lines 3 and 4,” said a DMRC officer.

“The server failure resulted in loss of train ID numbers and bunching of trains on Lines 3 and 4. Earlier, a similar snag had affected services, but not so badly. This time it took six hours to set things right. We had to cancel 10 trips between 10 am to 4 pm,” said the officer.

This was the fourth time this year that the Metro services had been held up due to a technical snag.
