'The high-level inquiry committee consists of three officers - general manager (maintenance), general manager (rolling stock) and general manager (signalling and telecom) - from the Operations and Maintenance Department of the DMRC,' he added.

The accident disrupted metro services between Yamuna bank and Indraprastha.

'The services on the route have been temporarily suspended as metro maintenance teams are working for the restoration of the site. We are currently checking the tracks and if there is any damage, resumption of services may take longer,' the official said.

The Indraprastha-Yamuna Bank metro line is the extension of the Dwarka-Indraprastha route.

However, the metro services between Indraprastha and Dwarka remained normal.

This is the second instance of a metro coach derailing within a span of one month. On Aug 12, a coach of a metro train went off the tracks on the Dwarka-Indraprastha route. There were 40 passengers on the train and no one was injured.
