Abt switch
The Abt switch is a kind of railway switch used on funiculars (inclined cable railways) that doesn't have any moving parts. It allows two cars to pass each other going uphill/downhill while sharing the same tracks. While most train switches rely on physically moving a section of track so the train goes one way or the other, the abt switch doesn't move at all. Instead each carriage has a grooved wheel which makes it turn left or right at a junction by sticking to the track on one side.
