You would have thought the signal allowing trains out of the bay
platform would be interlocked to the points being set correctly for
the route over the crossover, wouldn't you?


Even in the presence of a fault condition (which they've apparently
admitted)?


So much for signals being failsafe. Failsafe unless the failsafe fails.
Which it obviously did.


Exactly. If there was a fault with the points, he should have been on stop
and proceed at least, if allowed to move at all.

It was the equipment that was faulty.The points moved when they
shouldn't have. The failsafe of having points set and locked with a
green signal (in this instance) failed..
No procedure was carried out. That's all that can really be said until
the RAIB report comes out. When will it be a trilogy?

Some people within LU are fearful that a Clapham Junction type event
is round the corner
