My advice is to find a club that does1/8th scale and listen for a few weeks, watch and learn. Then If you still want to build this monstrous locomotive, go ahead, and while you are there build a trailer (as low to the ground as humany possible) to move it to and from the club. So you can have our loco and run it too! Good luck and if you don't like it you could sell it to a short line somewere
