Passengers travelling on the busy blue line of the Delhi Metro network, connecting Dwarka with Anand Vihar and Noida, experienced a stumbling ride on Tuesday due to a major technical snag in the system.
Several train trips were cancelled while others ran behind schedule due to the snag.
The train services were affected due to intermittent automatic train supervision (ATS) server failure, resulting in the problem of identification of trains, which are monitored through computers.
“The train services on Dwarka - Noida / Anand Vihar section were affected on Tuesday due to interlocking problem between Moti Nagar and Rama Krishna Ashram Marg metro stations. The snag directly affected train services between 11.42am and 12.35pm, on this line. However, the after effect remained till evening,” said a Delhi Metro Rail Corporation (DMRC) spokesperson.
Last month, DMRC had promised to ensure no service delay or disruption due to technical snag. It had also involved a group of scientists and experts from Korea and Germany to identify the reasons behind the glitches and worked on them so that DMRC can run the services without any technical hurdles.
However, it failed to keep its promise as there had been two serious complains of service disruptions on October 3 and on Tuesday.
“The train did not leave the station for about 15 minutes. Finally, around 2.25 pm the train moved but at a very low speed. When it reached sector 14, it was already 2.45pm. I got down from the train and came to my office at Kasturba Gandhi Marg in Connaught Place by an auto,” said Raja Sharma, a commuter who boarded the metro from Dwarka sector 9 at 2.10pm for Barakhamba Road.
Another commuter Rajesh Mathur said: “I reached Anand Vihar metro station at 12.40pm to catch a metro for Pragati Maidan. There was a huge rush of passengers on the platform as there was no train. The information board was showing that the next metro will arrive at 1.20pm. I waited for the train but till 1.30pm there was no train. Finally, I went out of the station and took a bus from Anand Vihar ISBT for ITO at 1.30 pm.”
A Noida-bound train that was approaching Kirti Nagar station around 11.42pm suddenly lost identification number and got stranded. The technical staff tried to sort out the problem but failed.
The Operations Control Centre (OCC) that controls and supervises the complex operation of metro had to run the train on manual mode at a restricted speed of 10 kmph.
A similar problem occurred with many trains. The technical staff resolved the problem around 12.35pm.
