Not looked at detail yet and might be day or so before I do, but I think you did well to utilise the presentation that you chose.
I think you interpreted "infrastructure" a bit narrowly; I'd have included an example of all the basic components of an aspect level, so therefore proving that the railway had no trains on it and that there was a defined end of the movement authority (probably both a visual means of knowing where this was phsically located- say an illuminated signal- and a way of intervening to ensure that train stops within the associated safety distance beyond that- say an active TPWS loop.
Like other IRSE exam questions, if you are good you will not run out of things to say in 30mins, so need to make sure that you cover the whole width of the question rather than concentrate on only part of it because you have the depth of knowledge that permits you to do so. Detail is good in at least some areas, but prioritise breadth of coverage.
I do not think that you absolutely have to put something in every box, but what about the need to stop traiins running whilst a crane is installing a bridge section (or indeed over lane message sign gantry) for the motorway running parallel and adjacent to the railway. Perhaps unlikely to be implemnted in circuits as not going to be a regular scenario presumably, but perhaos the "inclusion" could be purely procedural, with the signaller utilising a reminder appliance over the entrance buttons etc. ........

While I wrote this out in about half an hour, I had been thinking it over for quite a while before getting round to it.
