Here it is, with added comments!
As you realised, the thing that the examiners were really testing you for on this one was: how you'd cope with the two point numbers associated with the single slip. You didn't know quite how to deal with it but at least you showed you were aware.
Other than this I think a random eror of oversight which caused you to miss a few routes and what I think is a misunderstanding re where it is appropriate to time a train to a stand and release its overlap.
Certainly the better of the attempts.However Merlin was correct that these would be contenders for auto-normalisation or at very least an alarm to signaller if left reverse after passage of a train.
Also you need to think re what to do re Track Circuit Interrupters etc; I'd recommend covering this by a general note on a cover sheet or otherwise you need to remember each and every time that you use EL track on any of your CTs that it incorporates the TCI at 211A. One note could cover this and also the one at 202A dropping BF track.
