At least four people were killed and dozens of passengers were injured when their train partly derailed near the Alpine resort town of Garmisch-Partenkirchen in southern Germany, the authorities said.
The regional train was traveling to Munich when it derailed around lunchtime, the police said. A police spokeswoman said that there were about 60 people on the train, and more than a dozen of them were taken to a hospital with serious injuries.
Rescue operations took place with the assistance of helicopters from Austria, which shares a border with Germany in the Garmisch-Partenkirchen region, according to news reports.
Deutsche Bahn, the national railway company, said in a statement that the railway line was shut down between Garmisch-Partenkirchen and Oberau, a municipality in the district. Trains were being rerouted from Munich and other rail arteries.
Local news media showed at least one car spilling down the side of an embankment, as well as passengers sitting along the shoulder of a road near the tracks.
Law enforcement authorities and prosecutors were investigating the cause of the crash. It took place on the third day of a low-cost, nine-euro monthly train ticket plan by the government to help offset high transportation and fuel costs.
