At least 10 people have died and several injured in a train crash early on Wednesday near Madrid. After the incident, the rail service between Madrid, Ciudad Real and Andalusia was suspended.

The country’s rail system operator ADIF said that the crash happened in the province of Toledo at 9:00 AM local time.

“Traffic on the Madrid-Andalusia high-speed rail line has been suspended ​following a rear-end collision between two trains,” ADIF said in a message posted on X on Wednesday.

A southbound state-owned Renfe AVE train rear-ended a stationary Iryo train on the Madrid-Andalusia high-speed rail line. The impact sent carriages tumbling down an embankment.

The spokeswoman for the Castilla La Mancha region, Esther Padilla, said that although authorities can confirm 10 deaths, “that number will surely rise.” However, she said the cause of the crash is not known.

Padilla said that 397 passengers were in the Renfe train and 147 passengers in the Iryo train.
