Z-gauge British Rail Rectank, actually the ferry-fitted one with the larger wagon plate (though on the model, it is mounted on the bogie not the solebar for clearance). The model includes 2 bogies with couplings (add springs to the boxes to make them work) the tool tray to locate on the trussing, and a cage containing 4 axles of scale 2'6" wheels. Carefully clip the cage apart to remove the wheels, and even more carefully flex the bogie sides to put the axles in. You can buy spare wheels and bogies in another model in case you think you'll need them, or if you would like them for other projects. Rectank_BR_28_Z_38.stl
