GAUHATI, India (AP) — A passenger train has derailed in northeastern India, injuring dozens of passengers.

State-owned Indian Railways said in a statement that the engine and nine of the train’s 13 coaches jumped the track early Wednesday near the Jagiroad station, about 140 kilometers (85 miles) east of Gauhati, the capital of Assam state.

The cause of the derailment was not immediately known.

The statement said six of the injured passengers were hospitalized. Thirty-six others suffered minor injuries and were allowed to go home after receiving medical attention.

Railway accidents are common in India, which has one of the world’s largest train networks and serves 20 million passengers a day. Most collisions are blamed on poor maintenance and human error.
