Box Cab Diesel (N scale)

Box Cab B-B Industrial Diesel Locomotive (N-scale)Free-lance narrow-gauge box cab B-B industrial locomotive. This one-piece 3D-printed plastic body is designed to fit a Rokuhan Shorty SA-001-1 Z-scale chassis (available at https://ztrackcenter.com/SA001-1?search=shorty ). The body is held in place with two straight pins (not included) through the side sill. It is suggested the builder fabricate and install metal weights  inside the body as shown in the instructions diagram to improve traction, although the Shorty comes with built-in weights and traction tires. It is also suggested the builder install Rokuhan A019 knuckle couplers which are compatible with Micro Trains Line Nn3 couplers.
