The description is a bit vague, but it doesn't say that this piece should be placed in a city. I would say that this piece would be placed on a track piece where the switch occurs. It would be nice to have genuine Y pieces but this way is cheaper to produce.If my theory is correct, it would mean that you could build switches anywhere along a link - not just at city edges.
I suppose that you could use the crossover pieces with the tokens to represent the switch.
