Power system snaps, train comes to halt

It was one of the new metro trains inducted in the fleet just a week ago that developed electrical failure leading to disruption of services for almost two hours on busy Yamuna Bank – Dwarka 9 section on Sunday.
Delhi Metro officials said the auxiliary power system of the train failed immediately after it left the Rajiv Chowk metro station for Dwarka Sector-9.
The main power to the entire network comes from the overhead traction lines.
“As a result, the traction motor stopped getting electricity supply leading to complete darkness inside the train
and non-functioning of the air-conditioning,” a DMRC official said.
It was the second incident in just four days of a metro train developing electrical problem.
On Wednesday, the static inverter of a metro train stopped just before the Vidhan Sabha station on the underground section of Jehangirpuri – Central Secretariat leading to complete darkness in the train for about five minutes.
Delhi Metro Rail Corporation (DMRC) officials confirmed that both the trains that developed electrical problem have been manufactured by Bombardier Transportation.
DMRC is getting 81 trains (424 coaches) from Bombardier for Rs 3,000 crore for its 125-kilometre expansion in phase 2 of the Metro.
According to Sumit Singh, a media professional, there was loud sound and flashes of lights “3-4 times within 10 minutes” in the overhead wires of the metro line near Ramakrishna Ashram metro station.
“After that, the train moved very slow and it finally came to a halt at Rajiv Chowk station,” said Singh, who had boarded the metro from Dwarka Sector-9 station.
DMRC officials said train services on Line – 3 (Yamuna Bank – Dwarka Sector 9) remained affected for about one hour and 41 minutes between 3:15 p.m. to 4:56 p.m.
“At 3:42 p.m. the next train, which was immediately behind the affected train and was at Rajiv Chowk metro station, was cleared of passengers and used as a rescue train to recover the affected train after track clearance,” DMRC spokesperson Anuj Dayal said.
“Rescue operations got delayed substantially as some passengers ignored the train operator’s instructions, forced open the emergency exit doors and began walking on the track towards Rajiv Chowk and Ramakrishna Ashram stations. It severely hampered the relief operations,” Dayal added.
The Metro train was recovered by a coupling with the rescue train.
It was later withdrawn to the Yamuna Bank Depot for checking and maintenance.
