At least 13 passengers were killed and 45 injured when two trains collided sideways near Gorakhpur railway station in Uttar Pradesh on Tuesday night.
Later on Wednesday, railway minister Sadananda Gowda visited the spot and met the injured receiving treatment in various hospitals.
The collision took place at around 11pm near Nandnagar crossing, about seven kilometres from Gorakhpur, when Lucknow-bound Krishak Express reportedly overshot the signal near Gorakhpur station and hit the Barauni express coming from the state capital.
The north eastern railway (NER) has ordered a probe into the accident. It will be headed by commissioner Rail Safety P K Bajpai.
Two trains, Chauri Chaura Express and Maduadi Krishak, on the track were cancelled and the route of at least half-a -dozen trains was diverted in order to ease traffic.
Chief public relations officer of North- Eastern Railway Alok Kumar Singh said loco pilot of Krishak Express Ram Bahadur and assistant Loco pilot Satyajeet have been suspended pending enquiry.
The impact of the collision was so intense that three coaches of Barauni Express got derailed.
Prime Minister Narendra Modi expressed grief and announced compensation for the victims.
An ex-gratia payment of Rs 2 lakh each to the next of the kin of those killed and Rs 50,000 each to the seriously injured will be given from the Prime Minister's National Relief Fund.
The NER has announced Rs 50,000 to the kin of the dead, Rs 25,000 to those who suffered serious injuries and Rs 5000 to those who received minor injuries.
