MTH - Premier Freight Car Sets - 6-Car Coalporter Hopper Car Set - O Scale 3 Rail

The Coalporter is one of the latest evolutions in the more-than-150-year history of the American coal hopper. But technically speaking, it's not a hopper. It's a high-sided gondola, because it lacks the bottom-opening doors that characterize a true hopper. The only way to unload a Coalporter is to turn it upside down, which is exactly what happens at the rotary unloading facilities at factories and power plants served by Coalporter trains.
