S2 70T Roller Brng Trks Ho (KAD518)

HO-scale 70-ton roller-bearing trucks for vintage freight cars, designed to upgrade pre-1970 rolling stock with authentic detail and smooth, dependable operation.

These trucks feature a fully sprung suspension, metal sideframes and bolsters, non-magnetic metal wheels, and contoured insulated axles with RP-25 compatibility for free rolling. The 33-inch smooth wheels provide faithful, prototype-like markings and reliable tracking on standard HO layouts, making them a practical upgrade for almost any pre-1970 built 70-ton rolling stock.
