This addon implements a way to create a very fast train in your world. It only uses vanilla commands (in functions) and the vanilla minecarts (modified to work also in not from the player loaded chunks) - but don't worry, only minecarts with specific tags will be effected.
The highest speed is 40 blocks/second - for comparison: a minecart on a normal rail is only 8 blocks/second fast.
