The RAIB report into a near miss at Butterswood ABCL near Ulceby has just been issued and contains some interesting ideas.

Among its recommendations are :
[*] provision of a positive indication to drivers that the crossing has failed - ie it should tell the driver when it knows it has failed (rather than relying on him not to leave braking too late should the red light continue to flash), and
[*] evaluation of the practicality of remote monitoring of power supplies and key sub-systems.
If the former is implemented, it would no doubt reduce the risk of an accident or near miss of the type which occurred at Butterswood, but what indication would be likely (different from flashing red/flashing white) to tell the driver he must expect to have to stop? Steady red perhaps?
And if the latter can be carried to full implementation, would crossing faults effectively be handled the same way as AHB faults? Would we still need the Drivers Crossing Indicator ?
The report also contains recommendations to improve equipment reliability and driver training.
Whatever solution they choose, it's likely to mean a programme to modify/upgrade a lot of crossings.
