Describe the suggestion
When you model a track that includes more than just the track itself, the track will look sad on switches. Say you have any track with a trestle, so you would want to include the walkway, and the fences. Well, when you encounter a switch, you are forced to unrealistically create a model that lacks the realism of including the walkway and fencing on the straight bits of the track. The same thing is true of any models that include basically anything above the rail height itself.

Applications of the suggestion
Fixes switches on fancy track parts
