Commuters spotted repeated sparks and raised an alarm. "There were sparks earlier also during the journey. We raised an alarm, but nobody listened to us. After the train gates did not open for five minutes, we finally broke open the glass windows and came out," a passenger was quoted as saying by IANS.
In a desperate bid to ensure their safety, many passengers got out of the train by breaking the window glasses.
"As the lights suddenly went out there was a big commotion inside the train. Many children traveling in the train were terrified and started crying. There was an announcement in the public address system asking the passengers to get out of the train quickly," a passenger told IANS.
It took almost 20 minutes to evacuate all the passengers from the rake and metro officials claimed that no one fell sick.
This led to disruption of metro services for about half-an-hour after which south-bound metro services were started using the UP line, the CPRO said.
The flash was mainly because of the snag that led to power trip leading to the metro coming to a halt. We are investigating the matter, she said.
