Maybe all that's needed is the ability to allow travel beyond the end of a track node, which is something ORTS used to do by accident...
Have the leads to the turntable work like a buffer -- it's an end node as far as paths and signals are concerned.
Allow transit along the track's vector past the end node, and onto the turntable (which is in effect, an independent node that can change QDirections....), which would then allow movement onto the turntable without having to destroy paths.
You just wouldn't be able to extend a path onto a turntable, making it only useful in manual/explore mode.
The benefit of having the ability to move past an end node might also benefit routes with mixed dark/signaled territory, i.e. the signaled nodes would never intersect with the unsignaled nodes as far as the TDB was concerned, yet game play could cross between them.
