Minimum radius = 2nd radius

 

This plan is an extension of the plan included on the '6 feet wide' page, with more space that should allow a more realistic impression of the Caledonian Sleeper or Royal Scotsman. A run round loop in the lower part of the plan means that the top and bottom sections could even be split into modules, with a longer running length in between the two - perhaps round the garage or loft. The motorail siding is still in existence on the uppermost station siding.
