Hmmmm....
Always sounds good when the panel fails to show tracks under a fault.  Also
wonder how the diagnostic systems are arranged for that interlocking.  In a
perfect world, the fitters would know immediately something failed, and be
able to advise the signaller/train controller on the type of fault & time
to repair.

Noticed that, but the points at the down end need a hand crank to operate.
Must be some sort of peverse logic, but I can't see it. :o(

Reliability is everything.
