Diagram Alley

A couple of diagrams. First Cold Holt and then Penmouth Waterside. Both featured in a thread on RMweb for signalling advice. Apologies for image quality, the files get compressed by RMweb's upload process and there's nothing I can do about it (it seems to be something to do with their pixel width, not their actual file size).

 

Cold Holt is an interchange station between the S&P and the National Network. None of it exists in model form at present so it would be entirely new.

However, for Penmouth Waterside some of it exists already.

 

In the fiction it's a station that didn't exist originally when it was the site of a two loco engine shed and turntable with no loop, and just a single line through.

 

In heritage era a sizable expansion was undertaken onto empty adjacent port land. The turntable was moved and a decent sized engine shed put in, plus a locomotive works. The area immediately offstage below the bottom of the layout is supposed to be a service road and sea front so nothing practical can go there, which is why the signals are all 'inside' the layout. The two lines to the left are both bi-directional, and all three roads through are also bi-directional.

 

From a model and running perspective, the two central boards already exist from a previous layout build attempt, and as I only have 8 feet of operational scenic space where I currently live they have to be viable on their own without the two outer boards. Some of the track layout of that previous build is in situ and can't be moved (mainly the turnouts across the central board join) but the tracks below the shed (station and extra road) will be newly arranged (although it's going to be fun trying to lift and relay the C&L turnouts).

Note that some of the track (notably the shed access Y) is not joined up - this is because the available track objects in AnyRail don't fit with what's actually in place, which is hand-built C&L points with some subtle curves in them. There was no suitable Y so that's just a placeholder Peco Y.
