Switch Tracks are specially-designed tracks that are made to travel in one direction from one side, and travel in one of two directions from the other. When activated by either a Switch Lever or a Switch Motor, the track changes its direction from a straight line to a right-angle turn, or vice-versa.
Trains or Carts approaching from either of the two opposite directions treat the Switch Track as a normal turn or straight track, as the Switching mechanism only affects travel in one direction.
Switch Tracks cannot be operated by a Redstone signal directly, and must be connected to a Switch Motor in order to be operated remotely via Redstone.
Note: Turning on a high-speed switch track will not prevent an explosion if traveling at high speeds.
