Thanks for the feedback. Yes, I missed the 142A routes as I was far too focused on the B route after doing the route CTs, so it was an oversight. Must not do that in the exam!
I included the ES track in the release of the overlap as I thought the train could possibly occupy part of that track too, in case the driver stopped before getting right up to the signal. Was thinking it was similar to train stopping anywhere on DB or DC track when signalled onto the Up Loop. I can see now that there's no reason for the train to stop before getting to 142 signal (no platform).
A few questions:
Are the extra brackets marked on necessary? Also is it acceptable to use the same type of brackets, i.e () throughout, or is it standard practice to use the different types?
I was going to ask under which column should I have put 212R, as that's what I struggled with, but have now seen how Merlin showed it. I would have only put it against 211N to R though, as when 212 can be N or R when 211 N. Is that right?
Re the point to point locking, I had read about this in the notes, but wasn't quite sure about it. I have a better understanding of it now, but I have to ask why is point to point locking is not current, but pseudo point to point is?
I have taken on board the comments re auto normalisation of the points/alarm to signaller, and the TCIs.
Thanks again for your help. I've learned a lot already!
