Metro Services of Line 3/4 (Dwarka Sec-21 to Noida City Centre/Vaishali) were affected on Tuesday for about an hour when a portion of the OHE (Over Head Electricity) wire broke down between Janakpuri West and Uttam Nagar East station of the line going towards Dwarka.
The train services were mainly affected from 08:24 am to 09:47 am between Jankapuri West and Dwarka section of UP line.
However, the services from Jankpuri West to Noida City Centre/Vaishali Metro station were provided by running trains on a short loop on this section. To carry the passengers from Janakpuri West to Dwarka side, single line operation was also undertaken between Janakpuri West and Dwarka section.
In order to ensure the immediate repair/maintenance work of the affected OHE portion, four specialized teams comprising of 5-6 members each rushed to the site immediately form Najafgarh Depot, Airport Line Depot, Mundka Depot and Yamuna Bank Depot.
The idea was to ensure that if the nearest team gets stuck up in a jam or is unable to reach the site due to some other reasons then the other back up teams is on the way to carry out the urgent repair work.
In today's case, the Najafgarh and Airport line teams (nearest to the site) reached to the site at the earliest at 09:05 am and carried out the repair work in a very short time. The OHE was repaired and the normalcy of train services was restored on Line-3/4 at 09:47 am. All other lines were unaffected from this incident and train services were running normal.
Mangu Singh, Managing Director, DMRC has asked officials of DMRC to conduct an audit into the different types of electrical related failures on Line-3 so that the pattern of the failures could be studied and analyzed with the intention of finding technical methods to minimize the occurrence of such incidents as far as possible.
The audit will be conducted by a technical expert of the electrical department of DMRC who will go into the various technical aspects associated with each electrical failure of this line.
The Managing Director himself went to the Operation Control Centre (OCC) located at the Metro Bhawan, Barakhmba Road, to oversee restoration of services on the line.
