A polish hacker found out why trains did stop working. The manufacterer implemented a hidden electronic switch, which automatically activated after trains were serviced by a different company.

from the “i'll drm your arse” and “industrial sabotage r us” department, a true scandal: a polish train manufacturer used firmware to lock out trains at 3rd party service depots in order to disrupt the operations of the trains for the railways who did not choose to service the trains at the manufacturer's; at the same time they blamed the 3rd parties for their inability to properly service the trains.

further reading in polish (but translates via google well): more technical and less technical, but with more political/economical details.
