This is a much older version of Traincarts that is no longer maintained. You can find the up-to-date maintained TeamBergerhealer fork here.
This Minecraft Bukkit server plugin links carts together to form trains you can control! Public transportation redefined. :)
This old repository hosts a much older version of TrainCarts, suitable for Minecraft/Forge 1.7.10. TrainCarts uses BKCommonLib for a lot of the required functionalities.
BKCommonLib: v1.59
TrainCarts: v1.73.1
