Minecart upgrades

Minecart's need some upgrades! In order to make them a more viable as a means of transport, in comparison to the glider and horses. *Train- Give the players the ability to connect carts to create a Train, also give players an optional brake, rather than relying on de-energised accelerator rails to slow down or come to a stop. *Power or Hyper Carts- To encourage players to use carts as a means of transport, they need to be able to compete or offer something that the glider and horses don't. I believe a much faster cart that players can attach their carts to will offer this. For example, when one of these carts pass over an accelerator rail, they and any carts attached to them will travel 3x or greater, faster then normal. *Cheaper or more rails per craft- To encourage more use and/or over greater distances. *More Track and cart options- examples; Cross sections, remote/selectable track switching when approaching an intersection. A horse or stock cart, being able to place a lantern on a cart, a base cart ( not sure how this would work, but I think like a mini portal. When you enter it, you are transported into a small cart that you can build in and set up, such as a bed, chests, crafting tables. But if it's destroyed, everything inside will fall out, like if you break a chest). I believe things like this will make the use of carts viable and fun, building an elaborate and useful rail system across the lands.
