Train Crash in Bad Aibling: safety technology was not activated – THE WORLD

Transport Minister Alexander Dobrindt expressed concerned about the train wreck of Bad Aibling: He had never imagined that such disasters in Germany are possible. Initial investigation it is in fact a human error.

Because after the safety philosophy of the Deutsche Bahn, it is unlikely to be a head-on collision of two trains actually can get a single track. But are large electromagnets on railway vehicle and the track bed care.

Periodically, and at specific points on the infrastructure, such as signals, are located laterally in the track bed great track magnets. Now if a railway vehicle on which a vehicle magnet is, there are at the point with the track magnetic transmission and a comparison with the signal aspect.

backup to emergency brake to initiate

In the former railway jargon this backup technology called Indusi – inductive train protection. Today is spoken of Point type train control (PZB), because of the intervention or monitoring carried out in each case at certain points and not permanent.

” The accident site is difficult to access “

About track a train driver accidentally a signal at danger, this is detected by replacing the magnetic vibrations and immediately performed an emergency brake. In addition, the system monitors whether the permissible speed is exceeded at a certain point.

Even an emergency brake is triggered. There is also a Wachsamkeitsprüfung whether the train operator has a maintenance ankündigendes signal, a preliminary signal detected.

system was a week ago checked

But this security system is according to experts deal. A dispatcher or a platoon leader must have a possibility in exceptional situations to temporarily turn off the system, says an insider, who requested anonymity. For this purpose, but extensive measures and actions are required. The “Editorial Network Germany” reports citing investigators circles that exactly happened. A railway staff have the automatic signal system exceptionally overridden to “quasi by hand waving” a belated railcar yet. The driver went to this version so on, although the regular signal system was on red.

“Accidentally which is not turned off,” it says. Every technical system may have a malfunction and for there must be the possibility of eliminating it, is the reason for the possibility of being able to cripple the security system.

Allegedly, the security system on the misfortune route was technically examined only a week ago. And yet there have been no problems, explained the Group represented by Deutsche Bahn for Bayern, Klaus Dieter Josel, in Bad Aibling.
