The engine of Kashi Vishwanath Express derailed here at the New Delhi Railway Station while it was on its way to the yard, officials said on Saturday.
No injuries have, however, been reported.
According to officials, one wheel of the diesel engine of the empty coaching rake has derailed during shunting.
The incident comes as yet another addition to the spate of train derailments in the country, including the goods train derailment near Khandala in Maharashtra on September 7.
