Two trains collided head-on in Switzerland in the canton of Vaud on Monday evening, injuring as many as 40 people.
The ATS news agency reported that five of the injured were seriously hurt.
There are no reports of any deaths. But police said the driver of one of the trains was still unaccounted for and thought to be inside the wreckage.
The BBC reports the crash happened in Granges-pres-Marnand in Vaud canton, about 50km from the capital, Bern.
They were regional trains. AFP reports one was bound for Lausanne, about 38km to the south, and the other was travelling north from the same city.
Thirty eight people were killed when a bus plunged off a viaduct in Italy on Sunday and 79 people died in a train derailment in Spain last Wednesday.
