The two trains, local commuter services operated by a company called Meridian, collided at around 6:50 on Tuesday morning just outside Bad Aibling, approximately 60 kilometres south-east of Munich.
Ten people were confirmed dead as of Wednesday morning by police, with all missing persons now accounted for.
Around 80 people have been injured, including ten very critical, eight serious and more than 63 light injuries. Bavarian interior minister Joachim Herrmann spoke of rescuers having to deal with “unbelievable injuries” and needing psychological counselling after helping in the accident.

Fortunately, there were few of the children and young people who might ordinarily have been on the trains this week, because of the Fasching carnival holiday.
More than 500 people were involved in the rescue, including police, firefighters, ambulance crews and water- and mountain-rescue units. Some helpers came from neighbouring Austria to join the mission.

Ten rescue helicopters were on the scene, along with several more from the Bavarian and federal police.

The choppers were used to move the dead and seriously injured from the crash site, which was located in a wooded area by a river and inaccessible to ambulances.

Emergency crews have recovered two of the total of three black boxes from the trains. A third is expected to be recovered over the course of the day. That will allow workers from the Federal Railway Authority and state prosecutors to begin investigating the cause of the crash.

The stretch of track where the crash occurred was a curved, single-track section. It's unlikely the two drivers would have seen each other and had time to brake until just before the impact. Each train may have been travelling at up to 100km/h, transport minister Alexander Dobrindt said at a press conference.
But like most railway lines in Germany, the route is fitted with a PZB 90 system which is supposed to automatically activate passing trains' brakes if there is danger of a collision.
A Deutsche Bahn spokesman said on Tuesday that the system on this stretch of track had its last maintenance check around a week ago and no problems were found.

The system was fitted nationwide following an accident in Magdeburg in January 2011, when 10 people died in a train collision.
The Austrian state of Tirol has said that it would not send a group of 750 refugees to Bavaria who had been scheduled to travel on Tuesday, given the train crash's burden on the authorities.
