When a non-ATO train is held at 2407 sig (Sheung Shui Up P1) and it is not long enough to occupy both t/c's in the platform, if the train behind is ATO equipped it is allowed to buffer up behind it.



I assume, thus far, this is ok. However, the ATO train then completes station duties despite appearing to be only half in the platform! - Have I missed something?

The way L433 is behaving is possible, because follow-on route setting is available here (white triangle). A follow-on would allow an ATO train to pass the headway board (they are in effect platform shunt signals) and into a station where there is already another train. But you are right in that L433 shouldn't be allowed to take platform duties.

It is interesting that you should have P725 stuck at Red signal though. P trains are timetabled to not stop anywhere on the line, and correctly run, it wouldn't too (metro trains in front of a P train would always be routed in Sha Tin P1 to allow the P train to pass). A P train not run correctly will get stuck behind metro trains and be greatly delayed itself, as well as metro trains behind it, so it is worth doing everything you can to give them priority, intervene ARS if you need to.

What you can't see from the picture, because it is being hidden by the train list, is that there is a engineering possession taken on the Up line beside Lo Wu Yard causing a 'bottleneck'. There had also been a smattering of delayed trains (wrong kind of food trolley etc.) earlier further increasing the backlog.

In real life, how important is it that P trains are kept to time at the border?

In real life, there is often delay on the P trains crossing the border - mostly south-bound from the Chinese-side.
Hong Kong side is better as we ahere to the International convention that all local passenger trains should give way to International Trains.
The Chinese trains are slower in acceleration (They are hauled by a locomotive rather than being EMUs) than local Hong Kong EMUs and they don't have the benefits of ATO /headway board as they only use the conventional British AWS and follow the four/three aspect signalling)

In real life, doesn't the KTT trains (not the Chinese ones) use TBL ATP (but without ATO) within East Rail Line tracks? If such, do they drive closer to the preceding train or even make use of the headway boards?

KTT trains are run by MTR and it is Hong Kong trains. It is hauled by two locomotives both at the front and rear.
KTT uses ATP so they can also make use of the headway boards just as other local services.

I was talking about Chinese trains which still use the British AWS and colour line signalling.
