The crash occurred in a forested area near the town of Riedlingen in southwestern Baden-Wurttemberg state.

The place is located nearly 158km west of Munich city.

Charlotte Ziller, the district fire chief, told reporters, as quoted by Al Jazeera, that the three victims included the train driver and an employee of Germany’s state-owned rail operator, Deutsche Bahn.
