Underframe is in. Bolsters and centersill are pre-shaped parts. The sidesills and outer cross beams are scale 2x4s. The inner cross beams were made from some wood scrap I had lying around. I narrowed the bolster so the 2x4s fit over the sides, and sanded the angle on the top of the bolster flush. I also sanded the top of the bolster down even with the centersill, to lower the ride height with a pair of Weaver 3-rail trucks.
The white metal brake cylinders and brake levers are from Scale City Designs. The piping is from a roll of phos. bronze wire. I only represented the brake rigging that would be visible while the car was right-side up, and cut it back and kept it simple to avoid interfering with the 3-rail trucks again.
