I'm now accepting direct orders for Z scale locomotives. You can get a 44 Tonner, SW1200, SW1500, S-2, and S-1. These are custom orders so contact me via email at: thezmaker@gmail.com My SW1200, SW1500, S-2 and S-1 are all dual drive models! That means all eight wheels provide traction unlike my kits from Shapeways. These dual drive models are not available anywhere else. (The 44 Tonner is not dual drive) Visit www.thezmaker.com for more info. I also have a couple single drive locomotives in my Ready To Run Shop! Click here to order one of the items below.
