70-ton National Type B and B-1 Trucks from Plate C

Plate C National Malleable Type B 70-ton Truck

Plate C Model Prototypes is set to release 70-ton versions of the National Malleable Type B and B-1 trucks in HO scale. This is (to my knowledge) the first time these have been available in HO and perhaps, any scale. The fact that we will have both of these available is fantastic. The visual differences in HO are quite small. The B-1 incorporated updated trunnions that modified the arrangement (and appearance) of the spring package. The easiest way to discern the Type B from the Type B-1 is that the spring in the Type B "filled" the area below the bolster while on the B-1 you could "see" around the front spring and the B-1 also had a raised area around the small circles at the bottom of the sideframe casting, presumably for added strength. Again, subtle, but noticeable. IYKYK. These will be available from 3D Central

Santa Fe GA-55 AAR 65'6" mill gondola (Athearn)

Canadian National 48-foot mill gondola (Westerfield)

PRR H30 covered hopper; note that the left truck has the "early" teardrop shaped openings in the sideframe. It was not uncommon for cars and their trucks to become "separated" during shoppings of like cars. There are many examples of PFE reefers with two different prototypes of trucks under the same car.
