This American Car & Foundry 2,970-cubic-foot capacity two-bay Center Flow covered hopper no. 73048 (era: early 1990s+) kit is based on Accurail's new 2200-series tooling.
The covered hopper has a one-piece body and two sprues of detail parts. One sprue holds the underbody, stirrup steps, and two-piece outlet gates. The other has the slope sheets, draft-gear boxes, round hatch covers, air reservoir, control valve, crossover platforms, brake wheel, and brake rod/chain. The kit doesn’t include a brake cylinder, as those were located in the trucks on the full-size 2970s.
Completing the kit are roller-bearing trucks, Delrin engineering plastic wheelsets, Accumate knuckle couplers with modeler-installed trip pins, four 2-56 x 3/16” screws, and a steel weight. Written, illustrated instructions guide modelers through the 14 steps to assemble the kit.
