About "Transporters"
Transporters is a data pack that adds a few features to minecarts, activated by placing specific colors of wool underneath the tracks, as well as other cart-related features.
Lime / Red wool
Placing lime wool under the track will give minecarts an "engine" that continually makes them move at maximum speed.
The engine can be removed by placing red wool under a section of track. The engine is also removed when a cart leaves the track.
Purple wool / "endpoint" armor stands
To make carts fly through the air (and even through solid walls) towards a destination, name an armor stand "endpoint" and place it where you want the carts to fly to, then place purple wool under the tracks at the end of a railway, and carts passing over the wool will begin to fly towards the armor stand.
Keep in mind that if you have multiple armor stands named "endpoint," carts will only fly to whichever one is closest to them.
Orange wool
Placing orange wool underneath the tracks will destroy carts that pass over it.
Pink / Magenta wool
Pink wool will force nearby entities, including players, to ride carts as they pass over it.
Magenta wool behaves the same way, except it only works for players.
Use vanilla activator rails to force entities or players to dismount a cart.
"pointer" armor stands
Naming an armor stand "pointer" will turn it into a front-facing arrow attached to nearby carts.
This can behave weirdly if multiple carts are nearby, so using F3+B to show the hitboxes is recommended as an alternative.
Ladders / Shelves
Carts can climb ladders and wooden shelves, and will do so whenever they are in the same block space. The carts will also dismount at the top, in the direction they are facing.
Magenta Glazed Terracotta / Tripwire
Carts will change direction and move in the direction specified by the arrow on Magenta Glazed Terracotta placed under a tripwire beneath the cart. Perfect for turning carts around in a tight space!
This behavior does not work with rails due to Minecraft forcing carts to snap to rails, so you will potentially need to recover speed by placing lime wool under the next track section after a direction change.
