About 40 people were injured, five of them seriously, in a frontal collision between two passenger trains at a rural station in western Switzerland on Monday evening.
The driver of one of the trains is presumed to have been killed, trapped inside his cab, according to a spokesman for the Vaud cantonal police, quoted by the 20 Minuten newspaper.
The accident occurred when one train was entering the station of Granges-Marnand as the other was leaving. The line is a single track at that point and it is not clear why both trains were on it.
A number of ambulances and a helicopter were called in, and police and fire engines were also present at the site.
The Swiss Federal Railways set up a hotline for relatives and friends.
The line serves regional traffic between Lausanne and Payerne. Rail traffic was cancelled on the stretch between Moudon and Payerne, and the railway company laid on substitute buses. A message on its website advised travellers to take a different route, and warned them their journeys would take longer.
The message said the disruption would continue all evening.
