Thank you for those fascinating figures, which are presumably used by NR today. It would be interesting to drill down and find the root causes of accidents at gated crossings, and see what percentage were due to mechanical failure , presumably signals were fail safe. Did vehicles ram closed gates, or could human error on the part of the gatekeeper be possible? The risk seeking driver is probably not a completely new phenomenon, but encouraged by the apparent ease of dodging the modern barriers.
I believe it takes a staff of three to man a gated crossing, obviously a big expense compared to a remotely controlled barrier system- cost saving is obviously the main driver for modernisation. The District Council planners at Lewes have yet to be persuaded that removal of the grade 2 listed gates can be permitted, and have placed an injunction on NR : the station building, signal box and crossing gates were listed as a group of structures.
