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.
Surely it was still failsafe? No trains were signalled to collide with
each other.
