Thanks to Mikkel's help and a bit of lateral thinking, in that I could only save the screen print's in a format which I couldn't upload, so I ended up printing them off and scanning them in, here are two track plans for the environs of Brackhampton station.

This first one shows the overground approach with four tracks from left to righ the main up and down lines and then the relief up an down lines. These run into from extreme top to bottom, platform 12/11, bay platforms 10 and 9, platform 8/7, two through lines, platform 6/5, two more bay platforms 4/3 and at the bottom platform 2/1. Whilst looking very complicated the plan isn't finished and so far I've omitted the turntable, carriage sidings and cross over lines to gain access to them. Some of these are going to have to go. Building the access lines on a curve makes for very difficult geometry.

This one shows the opposite end of the station and again some rationalisation here as well as most of the point work will be under neath the city centre, consequently the fish sidings have been omitted as it would be impossible to work these. The top track splitting offo from the curve is intenede as an engine spur and again as it is underground there seemed little reason to keep it running along with the main line.

This is very much a first work in progress and bits will need printing off to get a feel for the size. But I've measured the area where the layout is going to go (when I've built the shed) and it should fit.

I was thinking for the opposite sie of having a split level fiddle yard with down and up lines on different levels.
