Despite their prevalence within the game's very name, mine carts and rails seem to have gotten the short end of the stick in terms of depth and variety. This particular mod, nicknamed Railcraft, aims to fix that issue. The railcraft mod for minecraft gives you a greatly expanded range of toys to play around with when constructing railways.
Useful for when you’d rather not go through the hassle of removing the track and placing the proper piece over the empty space.
So there you have it; a mod for any player who’s ever wanted to combine the merits of Minecraft with the construction elements of something like Rollercoaster Tycoon.
