RAIB on Waterloo collision

RAIB has confirmed it is conducting an investigation into the 15th August derailment at Waterloo.

The RAIB statement says:

The collision occurred because a set of points were misaligned and directed the passenger train away from its intended route. The misalignment was a consequence of a temporary modification to the points control system which also caused the train driver and signaller to receive indications that the points were correctly aligned.

Our investigation will examine:

  • the circumstances leading to installation of the temporary control system modification
  • the safety measures provided while the temporary modification was in place
  • the checking and testing procedures applicable to the modification
  • any relevant underlying management factors.
Bloody hell!

Eye thought the IRSE's vice like grip on signal testing was supposed to prevent this sort of thing happening?
