This car took quite a while to prep the white metal parts. The couplers that came with the kit would not fit the coupler pockets. I called Kadee, they ship #115 couplers with the kit now. I ordered a pack, 115's fit first try.
The underbody brake components although very detailed, will likely never be seen again. Some of the brake components interfere with the trucks/wheels. The truss rods are soft brass and bend if touched with any pressure. There are two more of these cars to build. I will choose the assembly sequence for these.
