I should mention that the layout is DC. As previously said, the base board has to lean against a wall in the loft when we have guests sleeping over. That limited the size because of an unfortunately placed radiator and the sloping ceiling.
What I've squeezed into the board is as follows:
There are three circuits of Hornby track. One each of first, second and third radious. Inside the first radious is a half circle of more first radious. There's also a siding from the first radious circuit ( where the double engine shed is located). The first and second radious circuits are linked by standard points ( one set on each long side). The second and third radious circuits are linked by curved points located on the short sides ( in the old photo, only the left one is in place). I've used insulated fishplates between the points, so that each of the three circuits is independently powered by its own controller ( cheap Hornby models).
Now here's where the fun begins. Outside of that is another circuit made of old Triang track (I spent ages down the garden cleaning it bit by bit). This is also third radious. On the left of the photo, a track branches off and goes around the edges of the board to the 'pier' at bottom right. To right of the Shankly island platform, a track rejoins the Triang third radious circuit. In the photo not all of the Triang track is joined, but it's an old photo.
The Hornby track and Triang track are not connected. I wanted to use some Triang track because I have a couple of old locomotives that are said to run better on the old style track because of their wheel flanges, and because I didn't want to buy too much new track.
