Well I did it legitimately.

Out of curiosity, how did the underside of the cart (the bit that attaches it to the rail) work? I have one that works for a one dimensional track, but two dimensions is beyond me.

Challenge: Make a monorail that goes up, down, left, right, forwards and backwards. Anyone who can do it without admin tools or any form of cheating gets free pie.
