The engine of the Pinakini Express train from Vijayawada rammed the platform at Chennai Central, which is a terminal station, causing cracks in the buffer zone.
There were a few tense moments as the train, which is supposed to slow down to a halt a few metres before the buffer zone, rammed the platform. Nobody was injured in the incident that happened at 1pm.
Sources in Southern Railway said the incident happened due to the carelessness of the loco pilot and an internal enquiry would be undertaken.
