S2 70T Roller Brng Trks Ho (KAD518)

33" smooth back wheels provide accurate markings with incredible detail that stays true to prototype standards. The non-magnetic metal wheels ensure high flexibility, while the sprung trucks and metal side frames contribute to fully sprung smooth tracking and free rolling capabilities. Contoured insulated axes and RP-25 free rolling wheels enhance performance.

The Barber S-2 70-ton Roller Bearing truck represents a logical development from the original friction bearing truck first introduced in the 1940s. Based on a prototype built in 1967, the design traces its roots back to the late 1950s. The robustness of the Barber S-2 truck is demonstrated by over forty years of successful service on the rails, and these trucks can still be found in interchange use today. This truck is compatible with almost any pre-1970 built 70-ton rolling stock.
