That can’t be true, can it?
Traversable doesn’t change if you bend parts of a track, and that can change the compass direction the switches point at.
For example, if part of the track containing a switch has an S shape, moving the switch from the center horizontal to the top or bottom one turns it by 180 degrees without affecting traversability.
