Re: HO Scale Freight Car Truck Document Update

Just to chime in, while it may seem odd that coal hoppers received roller bearings, remember that when they were new, they were experimental, and cost  a little more. Tests were often carried out on cars that tended to stay n home rails. There was a better chance of that with hopper and similarly UP’s stock cars.  Why go to the added expense of installing roller bearings on boxcars when they could wander off line for years, and you receive none of the reduced maintenance benefit during that time.
