Deutsche Welle reports. German police arrest man over rail ′sabotage′
A 51-year-old man in Germany was facing charges of attempted murder on Saturday after being “strongly suspected of having removed bolts on 80 meters (260 feet) of rail on a bridge between Cologne and Frankufrt,” prosecutors said in a statement.
Investigators are still trying to determine the suspect’s motives, while police on Friday said they could not rule out a “possible attack attempt.”
It could have resulted in a train derailing. Trains were canceled until the tracks could be inspected and “repairs” (made).
I’m going to go out on a limb and guess the motive is Terrorism.
