In the italian mailing list, the same question came up. There, one user 
pointed out that e.g. an ambulance car could switch tracks over stripes 
of paint, but not if there's a concrete wall.

This way, routing software would not show a possibility for the 
ambulance car to switch to a certain track because it thinks it's 
physically impossible,
