A Karachi-bound express train collided with a freight train in Pakistan's central Punjab region early on September 15, killing at least six people and injuring more than 100, Pakistani officials and media said.
The Awami Express hit a stationary cargo train at Sher Shah, about 25 kilometers from the city of Multan, and four carriages overturned, they said.
There was a delay in the emergency response due to Eid holidays in Pakistan, a mainly Muslim nation of 190 million people.
Railway official Saima Bashir blamed the accident on the passenger train engineer, saying he failed to heed a red signal that went up after the freight train had stopped.
She said the freight train stopped so the driver could remove the body of a man who tried to cross the track and got crushed to death.
Pakistan's colonial-era railway network has fallen into disrepair in recent decades due to chronic underinvestment and poor maintenance.
Last November, 19 people were killed in Pakistan's southwestern Balochistan Province after a train's brakes failed and it sped down the side of a mountain.
