The carts work the same as they do in singleplayer, and i dont have any minecart mods so they should be normal
I use a different kind of booster, it gives a large amount of boost
Its a door with a ladder, the ladder holds a minecart on the door, when you press a button the door opens and drops the minecart onto a sloped track where there is another minecart that get boosted, that minecart boosts the minecart you ride in, so its like double the boost
Also the boost is faster because it starts on a slope
The minecarts dont move until you press a button to call one up to you
When you get in you hit a stone plate which causes another booster to send the minecart off to the next station
When you arrive at a station theres 2 plates, a wooden one and a stone one, it uses an XOR gate (technically its an XNOR gate but more like !(XOR)), so when you get out the stone plate isnt pressed but the wood one is which causes another door to open and boosts the cart back into a holding spot where it all starts over
The holding spot can hold 3 or 4 carts, 4 carts maximum, so only 4 people can use a station at a time, its possible to make the holding spot bigger for more carts, but another booster would be needed to make it up the large slope that would be there
In its current design it looks like a mess of tracks, but you could build the boosters under ground, as long as the track that needs to boost the main cart that you ride in is next to part of the booster track
There was some weird slime glitch where i could see them but band couldnt
I could touch them to, but band couldnt
There were dozens of them, so many that i couldnt even walk through the tunnel
