Why the Eastbound Train Meet the Westbound Train?


German Train Crash Investigation Focus ‘On Signalling Error’


Investigations are looking at signal controller for clues on the Bavarian train disaster that killed 10 people.  The trains crashed head-on while both were travelling at about 100km/h (62mph) east of Bad Aibling, a spa town about 60km south-east of Munich.

Question that needs answer:

Investigators will have to find out why a train that left Holzkirchen travelling east to Rosenheim was on the single track at 06:48, four minutes after it was due to reach its next stop at Kolbermoor, where it would have met the westbound train on a double track.

The westbound train from Rosenheim to Holzkirchen would have left Kolbermoor at 06:45 and would have been expected to be on the single track at the time of the accident.

Signal controller’s role:

  • Safety system had been switched off to allow the eastbound train through on the single track line because it was several minutes late
  • PZB braking system is supposed to kick in when a train runs through a red light, provided the safety system is switched on

A police spokesman rejected the theory as “pure speculation”.
