Or depart from platform 3.

Thank you very much, this is extremely useful, will post a screenshot of the whole layout, but this morning I am thinking of altering a few bitsboth at the other end, which may alter the head shunt. The trap point is very timely as I am about to tiny up the turnouts on the middle board
Please could you explain the round disks and the square board

That is part of the reason for a bit of alteration, at the moment a departure platform only. Platform 1 departure, platform 2 arrivals, platform local arrival and departure via far left crossover

As I said basically its a scenic test track and storage sidings (not designed yet) for stock. This is the limit of the space available in my work room.
Could be extended in the future at both ends probably with fiddle yards
I am thinking of moving the trailing crossover, and or adding the access to the sidings on the upper main line opposite the start of the crossover giving a longer head shunt

James - might be a good idea to have a backing signal out of the main platform out towards the Home to allow an engine out of the main platform as one is leaving the bay. As a double track terminus, such a move might be useful. (A la Penzance as quoted earlier.
I also notice there is no facing entry into the bay which would be very restrictive. Good opportunity to replace a couple of points with a nice double slip! Or even a tandem followed by an outside single slip - we are tacking about "interesting track work developments" after all

Not sure about the triple ground signal, I think you could get away with two separate ones, one where the triple is and one at the next turnout. Bit simpler to build etc. As to the yellow one, the GWR didn't really do them, if a permissive one just don't have a red light but a clear one. Yellow ones came later in BR times. Adding some shunt ahead arms to the starters might be a good idea.
Outer home could be dispensed with as distances short as could the fixed distant.

My signalling experience is mostly ex-NER and BR North Eastern Region rather than GWR.
I did find a three disc GWR dolly via Google.
You still need to account for three possible routes.
Without the Outer Home the entire station throat is going to be in the Clearing Point which means you'll be unable to do anything once you've accepted a train and forever blocking back for many shunt moves.
Shunt Ahead signals are for Section Signals. The main aspects cover shunt moves, movements can always be flagged if the running line is occupied as part of the shunting.

You need to shove a few timbers here and probably in other similar places before you print. I’ve found that 3D printed track needs a different thought sequence to traditional build methods. With traditional construction methods you would often not shove every timber conflict to perfection before printing the templates as you can finish the shoving during the build. But you can’t do that with 3D printed sleepers as they cannot be shoved after printing. Believe me I’ve found out the hard way!

Multiple dollies did exist but in this case there are just 2 turnouts involved in the 3 routes, you don't need to signal them all in one go, simpler to signal each one.
The layout is small, if you are going to have an outer home it would be off stage. Do we know that the starters are not section signals? I think you will find that the GWR/WR used shunt signals etc to cover such shunting moves (see Vaughans book page 148 at Chipping Norton).
Personally I prefer the arm with an S (more interesting) but later iterations used a small arm which were used to cover a variety of situations each had a letter(s) to cover the issue. Man with a flag also works.
A Goods line loop or siding starter should have a O and the arm should be different, usually smaller and with different spectacles.

Thanks for the post, but I think I have said earlier this formation is both in the rough and I am now in the process of tidying up this formation/redesigning it, until I have finalized the plan its pointless to shove any timbers
There is a suggestion to fit in a trailing crossover which I am going to explore, firstly I am trying to not have any turnouts or crossings over base board joins, secondly I would like a longer head shunt into the sidings, thirdly they all need changing gauge to 0mf
But thanks for the observations

This week has been a bit of a nightmare as far as modeling is concerned, life has got in the way
A quick re-design, adding a slip to allow direct access to platform 1, change of position of access to sidings head shunt, no trap points added. Still in the rough and the first brick will have to be reprinted as both track end postilions have changed
Needs much more thought as I have noticed platform 3 can be lengthened

Taking comments into consideration, double slip added and by changing access to the sidings platform 3 has allowed platorm 3 to be lengthened. None of these really matter if used as a test track, but allows options
I have also brought the wood for the 6" end board low relief station concourse, should really cut the boards to their lengths (I have stripped them down in widths
John
I know at least 2 excellent exhibition layouts that started life as test tracks .... Or put another way, many a test track starts that way ...
Good luck and looking forward to seeing progress
Not sure if length is at a premium, but there is scope to shorten is considerably if the 3 left-most points are moved rightwards:-
Thus the point leading to the double slip becomes an outside single slip, and the point leading to the nearest road becomes a tandem. I know that is a lot of Templotting (I did my version when it was all hair-shirt and partial templates so I know!) and is much trickier to produce, but it would look great! And for those of us with an interest in track for its own sake a much more interesting project! Not to mention a tougher test!!
Best Wishes,
Howard
