Has a few buildings already accumulated over time from Xmas presents etc - cardboard Metcalfe PO331 train shed, small plastic Hornby station R8229, and a vacform plastic mountain of unknown brand with single tunnel through it that I can't quite work out where to place.
Most of this - except the mountain - is represented on the attached screencap from Anyrail. Ignore the obviously overlapping siding! Total baseboard size is 1m 73cm x 1m 15cm & can't really be extended as it has to go in a bedroom. The single loop currently on the baseboard is the outside loop on the diagram, so pretty much everything needs to go inside it or run the risk of falling off the edge of the world

There's not really a theme but the interest is in late 20th century British diesel. Has one of the Hornby Virgin Trains HST sets from maybe 25yrs ago which is pretty long but goes round the existing outside loop OK (not sure if it'd go round a tighter loop unless uncoupled) a Bachmann Class 20, small (Triang?) dock shunter and a few carriages. All analog control, and would probably like to keep it that way for cost & compatibility with cheap second-hand equipment. Has a two-track Gaugemaster controller with only one circuit being used. Open to adding another cheap controller for the shunting track if necessary. He'd like to keep the left-hand side of the layout free for some scenery, roads etc.
Any comments, suggestions, changes you'd make?
