There is this one rarely used turntable which is in an awkward location that is to only be used for a simple180 degree turn for the return run of steam engines.
Any simple concept that I may be overlooking? Does not need to go 360 degrees. Just a simple half turn.
I use the TT off scene. An engine goes into a single stall engine house which backs up to a forest then continues through the wall into the staging room, turns on the TT and then comes out of the engine house now pointing in the return direction.
