Metro services in national Capital were badly hit on Tuesday as movements of seven trains were affected with four round trip cancellations, two delayed and one partial cancellation on the Violet line connecting ITO to Escorts Mujesar due to erratic power supply.
Power supply at three sub stations tripped intermittently in the morning causing hardships to office goers stranded in trains and stations.
It was a “rare situation” when three sub stations tripped one after another due to problems of power supply causing cancellation of four round trips, two delayed trips and one partial trip cancellation on the line 6 (Violet line), said Sharat Sharma, Director (Operations) of Delhi Metro Rail Corporation (DMRC).
“Intermittent power supply failure from Haryana Vidyut Prasaran Nigam ltd (HVPNl) and Delhi Transco ltd (DTl) to DMRC’s sub-stations located at Faridabad, Sarita Vihar and Park Street led to tripping of Overhead Electrification (OHE). These sub-stations distribute power to entire line-6 for running trains and stations,” he said.
The problem began with power tripping at Sarita Vihar sub-stations at 8.11 am and immediately supply was restored from Faridabad substation which also tripped at 8.28 am. Supply tripped at both the sub stations thrice each, intermittently, affecting the train movement.
To tackle the situation, power supply was restored from IP Extension substation but it also tripped for five minutes at 8.25 am. Finally power supply was restored at Faridabad substation at 9.42 am and situation normalised at 9.49 am. For three minutes, between 8.25 am to 8.28 am, there was no power available, said the official.
Metro services in the recent past have been hit due to one or another reason.
