O Gauge Trucks & Truck Parts

An early freight truck with distinctive built-up side frames, commonly associated with older railroad equipment.

An early cast freight truck design found on rolling stock representing the first half of the 20th century.

A familiar cast freight truck style widely associated with 20th-century freight cars and frequently modeled in O Gauge.

Trucks using roller bearings at the axle journals, commonly associated with later and more modern freight equipment.

Older trucks representing plain journal-bearing arrangements used before roller bearings became the railroad standard.

Passenger equipment uses specialized truck designs, including both four-wheel and six-wheel arrangements depending on the car and prototype.

O Gauge replacement trucks can incorporate additional features that are important when choosing the correct assembly. Some rolling stock uses truck-mounted couplers, including operating couplers, while lighted or operating cars may have pickup rollers or other electrical contacts mounted to a truck to collect power from the track.

You may also encounter sprung trucks with visible or functional spring arrangements and die-cast trucks made with metal components. These features can affect appearance, weight, operation, and compatibility, so replacing a truck often involves matching more than its basic shape.

Check the manufacturer, model or car number, mounting arrangement, wheelbase, wheel size, coupler configuration, and electrical pickup requirements when applicable.

Original part numbers and service diagrams can be particularly helpful when restoring older O Gauge equipment.
