This kit includes a resin cab, pewter frame, laser cut deck and roof, and photo-etch parts with option for open or closed doors. This requires Micro-Trains Z scale trucks with short shank coupler (not included). Some short shank couplers in these versions are: Arch Bar, Andrews, Barber and Bettendorf. And they come in both black and brown. Your choice. Probably, I would choose the Arch Bar trucks in black and weather them with rust colored chalk. Click "instructions" tab to see more detail.
