    We found that the PLC code actually contained logic that would lock up the train with bogus error codes after some date, or if the train wasn't running for a given time. One version of the controller actually contained GPS coordinates to contain the behaviour to third party workshops.

    It was also possible to unlock the trains by pressing a key combination in the cabin controls. None of this was documented.
