Product details

Equip suitable HO rolling stock with arch-bar trucks and truck-mounted couplers using Kadee 503. This pair combines the older braced sideframe style with 33-inch ribbed-back wheels and No. 148 couplers.

Features and package contents

  • Two assembled metal trucks with sprung bolsters and 33-inch ribbed-back wheels.
  • Code 110 (0.110-inch-wide) nonmagnetic RP-25 wheels, insulated axles and No. 637 springs.
  • Includes two No. 148 couplers, two gearboxes with lids, two 0-48 screws, two insulating bushings, two No. 209 washers and two No. 622 springs.

Compatibility and installation

Check the exact car and mount on an appropriate flat bolster with suitable No. 2 or 2-56 screws; truck-mounting screws are not included. Assemble the supplied couplers onto the truck platforms before use. Check wheel gauge, clearance and coupler height. Code 110 is wheel width, not rail height. Car and track are not included.

Small hobby parts; intended for modelers ages 14 and older. Manufacturer warning: cancer and reproductive harm.

Condition & collecting

Match the listed scale and track gauge to your layout. For locomotives, check the power system, decoder and sound details; DCC ready does not mean a decoder is installed. For rolling stock, check couplers, clearance and the manufacturer's minimum-radius requirement where provided.

Shipping & returns

Shipping, taxes and any applicable discounts are calculated at checkout.

Why these products?

We match the recorded product type, hobby, scale, maker and casting where those details are available. Explicitly selected items come first. Custom builds, loose cars, DIY kits and parts stay in their own lanes. Matching scale or brand alone does not prove compatibility.

Prices and availability are confirmed at checkout.
