As you suspected, although almost everything you did was right, it wasn't anywhere near enough to answer the question.
You showed the crossing itself, but not the approaches ; think about what the motorist sees as they approach the crossing in terms of signage, road markings etc. and don't forget that there is something important AFTER an AHBC.
Also should have indicated enough about the rail approach to explain how the 27 seconds warning time is achieved. Yes you have shown a treadle but you have not indicated its purpose, or indeed if it is only one of several on each side of the crossing. Actually I'd have chosen a double track line as it gives you more scope re displaying your knowledge when answering the question. [Not sure on the single line you depicted a 2nd train will approach the crossing- likely to be a head-on collision before it gets there !]
Review also your diagram re the placement of the telephones and indeed the omission of audible warning.
In your description (which I think ought to be at least 2 sides of A4 handwriting at minimum to be able to get 18 marks, assuming the remainder are for an extended drawing), you should have included:
a) how the activation achieved
b) how the barriers lower
c) what causes the crossing to normalise after passage of train
d) more in depth discussion re hazards identified and indeed more hazards, particularly concerning the road user, but also think of the rail driver and equipment malfunction.
Certainly on the right lines but not substantial enough.
Amongst other sources I suggest you look at:
http://db.tt/S1OMXQ4B
and
this attempt at the 2011 mock exam
and
this attempt at a 2010 question
and
something we did at GM Rail event some years ago which should help with the hazards
and
this guidance from the ORR , in particular there is a diagram on page 73 that should help improve yours from the road user perspective.

I have just started doing some work to prepare for the IRSE exams. I haven't done much work on level crossings before but it seems like a popular topic so thought I would have ago at one of the questions. I don't feel like I have written much so I might have missed a couple of things. Any feedback would be welcome.
Thanks
