Services on the Delhi Metro's Dwarka-Noida route came a cropper yet again on Friday morning due to a technical snag, leading to train cancellations, delays and overcrowded platforms.
More than one lakh commuters travel on this corridor that connects Dwarka with Anand Vihar and Noida during peak hours every day.
"Interlocking problem in several trains led to loss of their identification numbers leading to trains clogging the platforms. We had to run trains manually at a restricted speed of 25 km per hour," a Metro spokesperson said.
Technical snags have dogged the corridor several times in the past. The last incident occurred just 10 days ago on October 19.
On Friday, several trains were cancelled and many ran behind schedule.
The disruption was caused when one of the servers powering the intermittent automatic train supervision (ATS) failed, making the identification of trains difficult. It took more than two hours to fix the snag.
Commuters faced a harrowing time. Office goers were livid.
"How can one depend on the Metro, especially when snags occur during office hours? At times, the Metro is more problematic than a traffic jam," said Sandeep Sharma, an architect, who travels by the Metro to work every day.
Many commuters alleged the trains ran late till late afternoon, even after "normalcy" was officially restored.
A DMRC official said the spate of snags on the same corridor are "isolated incidents".
"It could have happened anywhere else," the official said.
