FRANKFURT: A train derailment in a wooded area of southwestern Germany that killed three people on Sunday may have been caused by an overflowing sewer, local police and prosecutors said Monday. “It is believed that heavy rain in the area of the accident caused a sewage shaft to overflow,” Ulm police and Ravensburg prosecutors said in a joint statement. “The water triggered a landslide on the embankment next to the tracks, which in turn caused the derailment,” they added. About 100 passengers were aboard the train when the accident occurred at around 6:10 p.m.

The cause of the crash, near the town of Riedlingen in Baden-Wuerttemberg state, remains under investigation. Around 100 people were onboard.

Two cars of a passenger train derailed in southwest Germany on Sunday night, killing at least three people and injuring 34, according to emergency services.
