A train traveling from Lahore to Rawalpindi overshot and ran aground on a closed track in Gujranwala on Thursday evening, killing at least four people.
Rescue services said that at least nine people are still trapped under the train.
The wheels of two carriages of the train are buried in the ground, and the floor of the train carriage is level with the ground.
Authorities have also requested for heavy machinery required to pull the train back onto the track at the Gujranwala railway station.
Railways minister Khawaja Saad Rafique has also ordered an inquiry into the incident. He added that he is personally supervising the rescue effort.
The train was traveling from Lahore to Rawalpindi and did not stop at its designated point, and overshot over a closed section of the track until it hit an electric poll. The track was surrounded by thousands of people from the locality.
