A spokesman for German railway company Deutsche Bahn said that two trains collided on a single-track section near Bad Aibling.
Police spokesman Stefan Sonntag told that this is the biggest accident they have had in years in this region. Many emergency doctors, ambulances and helicopters reached the spot of accident and started rescue operations.
Among the dead was the driver of one of the trains, according to Bavarian Bayerischer Rundfunk broadcaster.
The driver of the other train is missing, though police pointed out that he could hardly survive a collision of this kind.
In 1998, Germaany's worst train accident took place claiming 101 lives and injuring more than 80, when a high-speed ICE train crashed in the northern German town of Eschede.
