The incident took place near Sarhari railway station in Nawabshah. Rescue teams and police officials have rushed to the spot.
“According to the information so far, 28 passengers have been killed and many are injured,” Pakistan railway minister Khawaja Saad Rafique told reporters, adding at least 1,000 people were aboard the Hazara Express when it came off the tracks.
A spokesperson of the Pakistan Railways in Karachi said at least eight bogies derailed and the intensity of the accident increased due to delayed application of brakes.
Television channels showed the crash site near Sarwari railway station with the train compartments badly damaged near the station.
Additional troops have been called in to assist the rescue operation. Army Aviation helicopters are also reaching the spot to rescue the injured people.
“The rescue operation of Pakistan Army will continue till the transfer of the last injured to the hospital and the rehabilitation of the people trapped at the accident site,” it said.
Officials said the affected bogies would be lifted off the track in a few hours using heavy machines and added that trains departing from Karachi might face delays.
Federal Minister for Railways and Aviation Rafiq said the train, carrying over 1,000 passengers, was travelling at a reasonable speed, which initial investigations showed.
In June 2021 two trains collided near Daharki in Sindh killing at least 65 people and injuring about 150 others.
At least 75 passengers burnt to death in a fire aboard the Tezgam express train in October 2019, while a two-train collision at Ghotki killed more than 100 people in 2005.
