CraftBookMinecart More Rails
More Rails is a minecart mechanic that adds new rail types, through the use of other blocks.
When minecarts pass over pressure plates, they will be given a continual speed boost so as they don't come to a complete stop. This can be used to create 4-way intersections, with the pressure plate being in the centre and the rails all facing it.
When a minecart runs into ladders or vines, the block acts as a vertical minecart rail and propels the minecart upwards by about 1 block.
