- 'Michael P' was playing a game on his phone before collision killed 12 and injured 89
- He was sentenced to three and a half years in jail by a court in Bavaria
The 40-year-old man, identified by officials only as "Michael P," signaled for two trains coming from opposite directions to travel on a single track.
According to German authorities, he was playing a computer game on his phone shortly before the February 9 head-on crash near the spa town of Bad Aibling in southern Germany. The two trains were traveling at speeds of 100 kph (60 mph) when they collided.
The controller was arrested on suspicion of manslaughter and gross negligence in April. Investigators said his actions were a "dereliction of duty" that distracted him from controlling the train traffic.
