Re: Question about operations on my layout / signal positions

Given that you have goaded me into waffling... (Albeit a couple of years ago...)
(Other people might like to have a look at some of the other possible information...)
Assuming that you go for a Down Bay (with wild, eager enthusiasm) the points into it would have a Facing Point Lock - which would have a "Lock Bar" along the nearside rail immediately before the toe of the points. This would work with the FPL on the same (Blue) lever. Its job is to prevent the points being changed while anything is on them.
Signal numbering and naming ... All companies numbered 123 and on left to right. Anything that had to be added later could well get A, B, etc at the low number end. EDP levers in a sub frame might not be numbered but could be A, B. EDPs are not interlocked with the rest of the levers.
The usual practice - which would apply here - is for the Running Signals to be at the outer ends of the frame - the lowest and highest numbers.
If you have Up line slotted Distant(s) for the junction Box you would also have the Down station Distant(s) slotted under at least some of the Junction's Down signals - possibly both Outer and Inner Distants. A slotted Distant coming from the Branch would almost certainly be Fixed Distant(s) (under the Branch Home(s) ).
Unlike the rest of the Big Four the LMS, followed by the LMR adopted a practice of only calling the last Running signal of Station Limits (the Section Signal) a Starter. All the Running signals before that were identified as Homes - Home 1, Home 2, Home 3 and then the Starter. This would make your Platform 2 signal probably Home 2 or possibly Home 3 - but being Home 3 would require Track Circuiting at least between Homes 1 and 2 - and probably in the platform and as an arrival TC In Rear of (before) Home 1. Provision of Outer Homes impacts on line capacity / headways.
