Controller ‘hit wrong symbol twice’ in deadly sight crash

“An generally comfortless stringing-together of dual mistakes” had caused the crash, Bavarian interior apportion Joachim Herrmann told Bild on Tuesday.

The controller initial incorrectly authorised both trains to entrance a single-track widen where they would be forced into a head-on collision.

But he compounded his blunder by promulgation a wrong vigilance to advise a drivers.

“When he beheld his initial mistake, a controller attempted to send a initial warning radio vigilance to both drivers,” Herrmann explained.

“Perhaps out of agitation, he though pulpy a wrong button. The summary went to a other controllers in a evident area, who called him back.

“He sent a second vigilance to a sight drivers, and this time he pulpy a right button, though by afterwards it was already too late,” Herrmann said.

“If a initial vigilance had reached a drivers, it competence still have been probable to have stopped a accident. That is generally tragic,” he said.

The controller now faces charges of inattentive murdering over a crash, one of a many critical in complicated Germany.

A tiny china backing for rail user Deutsche Bahn is that there were no technical defects on a lane or a control systems, such as a PZB involuntary braking system introduced after a identical collision in Magdeburg in 2011.
