	Switcher signs can read information from the train or cart above and toggle a lever and rails based on that. It also marks the switchable nodes of the [[TrainCarts/PathFinding\|path finding]] routing network. This makes this multi-purpose sign important for routing trains to their destinations, whether using path finding or otherwise.

	The switcher sign is also used during [[TrainCarts/PathFinding\|path finding]]. If a train or cart has a destination set, and no statements on the sign match (or no statements were set), it will toggle the rails to make the train go to the requested destination. If you need to force an alternative route or need to send 'passing through' trains around, add a statement on this sign to do so.

	By using a <code>[-train]</code> passengers switcher sign, the lever is automatically toggled down once a player enters the train. This signal activates an inverted station sign, causing the train to launch into the opposite side that is powered. In this setup this launches the train left once a player enters. A redstone repeater delay can be used to debounce this.		By using a <code>[-train]</code> passengers switcher sign, the lever is automatically toggled down once a player enters the train.
