A SABOTEUR had time between trains to carry out the '10 minute job' needed to alter the Potters Bar points to derail a train, according to the maintenance contractor responsible for the points.
Jarvis hit back at suggestions that poor maintenance was to blame for the crash and dismissed the view that sabotage was unlikely because there was not enough time between trains for a saboteur to get on to the track and adjust the points.
A spokesman for the company said: 'There are 40-minute gaps between the trains through the night so there is plenty of opportunity for someone to do this 10-minute job.'
The claim adds weight to Jarvis's suggestion that the points derailed the four-carriage commuter train because a saboteur with insider knowledge had tampered with them.
The contractor also confirmed that an '18-inch adjustable spanner available at any high street DIY shop' could be used to adjust the points.
The contractor said it was not saying sabotage was to blame for the crash but stressed the theory should not be ruled out.
