A train crash in eastern India on Friday was the country’s worst rail disaster in two decades, killing more than 230 people. It renewed questions about rail safety in a country that has invested heavily in the system in recent years after a long history of deadly crashes.

238 people confirmed dead

A passenger train derailed and struck two other trains in the Balasore district of Odisha state, officials said. The state’s chief secretary, Pradeep Jena, said on Saturday that 238 people had been killed in the crash and that 900 more had been injured. With rescue efforts still underway, the toll is likely to rise.

The crash occurred when several cars of a train derailed and hit a second one, the train’s operator, South Eastern Railway, said in a statement. Local officials said that a third train, carrying freight, was ultimately involved, but details of this were not yet clear.

One of the trains involved was a Shalimar-Chennai Coromandel Express train, according to South Eastern Railway. The Coromandel Express service has been known for connecting the biggest cities on India’s east coast at relatively high speed.
