"One wheel of diesel engine of empty caching rake has derailed at NDLS station during shunting movement to washing line. There were no injuries," said Neeraj Sharma, Northern Railways spokesperson.
The derailment comes close on the heels of three trains jumping off the tracks in Uttar Pradesh, New Delhi and Maharashtra within a span of nine hours on September 7.
After this, Railway Minister Piyush Goyal asked the Railway Board to divert rails marked for construction of new lines to stretches prone to accidents and where replacement was due.
