Other surprises were soon discovered. Among them was the blocking of a train when one of its components is replaced (verified by its serial number). An option to undo the lockout was also discovered – this did not require setting flags at computer memory level, just the right sequence of button clicks in the cab and on the on-board computer screen. When news of the successful launch of the Impulse hit the media, the trains received a software update that removed this ‘fix’ option. On another train, a code was found instructing it to ‘break down’ after a million kilometres.
