I've noticed the news today Re: A Cleaner stole a train and crashed at a nearby house. (See link for the BBC News above). I wonder how a cleaner lady (in her 20s) managed to steal a train from a depot and took it for a joy ride for a mile before coming off the track and hit a house.
There are plenty of systemtic failures to allow this to happen. For a start
(1)The train system should not be able to operate by others except the Driver(s) or a qualify person.
(2) The train should have been tripped (if the ATP system is in use), and not be allowed to drive off from a Depot.
(3) The control system at the depot should have picked up this unauthorised move and stop it there. (perhaps with a trap point?)
(4) Similar to (2) IT should have got tripped as soon as it entered the main line section. The train must have travelled fast enough to leave the track section and hit a house!.
