70-Ton A-3 Trucks
With insulated metal RP-25 contour wheelsets.
American Steel Foundries’ A-3 Ride Control truck was arguably the most successful design ever. Plain bearing versions were manufactured from the mid 1940s to the mid 1960s. The 70-ton trucks featured a 5’-8” wheel base and 6” X 11” journals. Examples of 70-ton capacity cars built during this era were 3-bay hoppers, 2 and 3-bay covered hoppers, mill gons and some flat cars.
