Hello minecrafters, I was a little bit bored, so I made a world with some minecart boosters <Door boosters/2 way boosters/Smart boosters/C booster/Other> I did not design thease boosters, I just got them from here (viewtopic.php?f=1020&t=149865#Booster%20Designs) and built them into a world for easy access and testing wich would be good for a building/space or whatever you choose.
