I have attempted Q4 from the 1994 paper (also in the Mod 3 study pack - section on level crossings)
The question was:
An automatic level crossing requires modernising because development of the surrounding area has given it significant commuter road usage. The crossing is situated 100 metres (110 yards) from a station platform, at which alternate trains stop. Describe the interface between the crossing and the signalling, for a bi-directionally signalled double line without pointwork.
I'd welcome any comments, particularly on whether I've even chosen the right type of crossing for this situation, and whether I've taken the right/best approach to the question. I realise now as I submit this that a diagram at the beginning probably would have helped, but I'm just submitting my answer as it stands.
