"There was some problem with the track circuit on the Blue Line. Due to that, the trains were running at restricted speed. But the problem has been rectified now," a Delhi Metro Rail Corporation spokesperson told IANS.
"Trains were running at restricted speed on Line 3 (due to Track Circuit Failure) and Line 6 (train motoring issue) leading to bunching. Services are now becoming normal as the bunching is cleared," the official added.
The problem lasted from 8 a.m. to 9 a.m., causing a huge rush at the metro stations.
"There was a ruckus at Noida Sector 16 metro station. Hundreds of passengers were stuck at the exit doors. I was already late for office and it took me another 15 minutes to exit the station," said Rajiv, one of the commuters. (IANS)
