Depending on how you work the slip coach, it could also be used in shunting that to/from a branch train.
I was certainly missing an calling on arm for the Bay Platform on the branch home bracket - so I added one. Is that the only place you meant?

However, perhaps you intend to do it in P2, hence the calling on for that platform?
Well, yes, I did intend that to be a platform 2 operation, but now thinking about it, that is a long way round for an express, isn't it? So I added one to the Up home bracket home for Pl1.

Actually I intended those for shunting out onto the Up as it is "wrong direction" working. That's incorrect, I take it? I now realize that I subsequently added the two stacked ground discs that control the exit onto Down and the Up from the road as well, so that's all certainly odd. I have removed both the subsidiaries on the RHS platform starters and those stacked discs and substituted a home (for the Down) with a bracket arm holding a miniature arm (for moves to the Up). As you pointed out, that could include a passenger coach being moved to Platform 1.
For Platform 2 moves shunt moves on the down, the Pl2 starter will have to be cleared. which is OK as there is an advanced starter. The alternative would be no AS, shunt signal + shunt limit and lots of "Shunt Ahead" bells, I think. Right now there will be "Blocking Back Outside Home" for all shunt moves to the Up and "Block Back Inside Home" for goods moves from Down to Up via the trailing crossover into the Brewery, which I could convert into only needing BBIH just for the coach working to Up by adding an outer home on the Up? The same applies to the Branch as well?
Edit:
Actually, thinking about it, the shunt moves to the Up for a coach to be added to an express would be done under cover of the TOS not having been sent yet to the previous box (in this case Trefor), so no BBOH in that case.

I've never seen stacked discs when a yellow disc was involved, but it almost certainly happened somewhere (cue new thread discussing examples?).
Also - what is the alternative you would suggest? In this case the route indications are to the Branch and (via the crossover) to the Up both for departing goods trains or shunting locos to the branch only. Those could have arms on a bracket or just a vertical arrangement of miniature arms, of course, but how would the shunting line be indicated - by a third arm that is nearly always pulled off, perhaps?
