Rescue efforts have ended for India's worst train accident in more than two decades, which left at least 261 people dead, officials said Saturday.

A passenger train derailed and hit another one on Friday in the eastern district of Balasore in Odisha state. One train also hit a freight train parked nearby, resulting in a disastrous wreck of mangled rail cars and injuring 1,000 people.

A preliminary government report identified a possible signal error as the cause of the tragedy, Reuters reported.

The death toll has reached 261, according to a spokesperson for South Eastern Railway.

The Indian government will compensate families of the dead with 1 million rupees ($12,000), while the seriously injured will receive 200,000 rupees and those with minor injuries get 50,000 rupees, Railway Minister Ashwini Vaishnaw said.

"It's a big, tragic accident," Vaishnaw was quoted as saying by Reuters. "Our complete focus is on the rescue and relief operation, and we are trying to ensure that those injured get the best possible treatment."

The collision occurred around 7 p.m. (1330 GMT) on Friday when the Howrah Superfast Express from Bengaluru to Howrah in West Bengal collided with the Coromandel Express from Kolkata to Chennai.

After an extensive search-and-rescue — involving hundreds of fire department personnel, police officers and National Disaster Response Force teams as well as sniffer dogs — authorities have ended the rescue operation. Workers have started clearing debris to restore rail traffic.

Indian Railways says its network transports more than 13 million people every day. But critics have called out the state-run monopoly's safety record, pointing to aging infrastructure. 

Indian officials quoted by Reuters described the accident as "extremely tragic" and called for rail safety to be the number one priority for the rail network.
