About "Transporters"

Transporters is a data pack that adds a few features to minecarts, activated by placing specific colors of wool underneath the tracks.

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.

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.

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.
