Check it out, this is my Warp Jump Simulator that I built underground.
There is a teleport at the end but it won't take the mine cart with it.

NOTE: The warp jump is just a small piece of the puzzle.
This map has a lot of spread out structures and rails every where.
There's even an adventure waiting to be found in the jungle near my
jungle home.

EDIT: Coordinates for the Warp Jump entrance are
X: -107.20
Y: 74.00
Z: -549.69
