501 Arch Bar Standard (KAD501)

HO-scale Arch Bar Trucks with 33-inch ribbed wheels reproduce the late-19th to early-20th-century arch-bar design for freight cars. This paired set combines authentic detailing with modern performance, featuring metal sideframes and bolsters, fully sprung suspension for a lifelike ride, and RP-25 free-rolling wheels that are non-magnetic for smooth operation on today’s layouts.

Ideal for period-era equipment, these trucks capture the look of early interchange service and lines such as logging or industrial rails that didn’t operate under common-carrier rules. Contoured insulated axles and precise wheel alignment help models track smoothly around curves, delivering a convincing, historically accurate finish to vintage HO rolling stock.
