The biggest shame is the lack of availability for those of us with large roads who are modelling American unit trains.
Between NOS and the selection of used & warranty repair kits from eBay that were available, I’ve amassed a fleet of approximately 30 of the centerflow hoppers. I still would like to get a couple of the new B&O ones though. The shame is that the LGB 3-bay is almost the same price as the USA 4-bay. And we all know which one is far superior in quality. The only advantage the only advantage the LGB version has over the USA version is that of durability of the (few) details it has.
I really wish either USA or Aristo would have managed to get the molds for those cars, they would have sold like hotcakes.
