I'm struggling with part 2 (iii) of this question which asks to "Describe the potential impact on the strike in distance of a change to a cab signalling system". (This is for a crossing with four barriers which close the road completely, and barriers close automatically).
It's only worth 2 marks in the question so don't need to say too much, but I really don't know much on this topic. Is information such as strike in points easily updated in cab signalling systems?
Thanks.
