Improve the Appearance and Operation of Your HO Freight Cars
Kadee-brand trucks have metal wheels that conform to the NMRA's RP-25 contour, so they roll through turnouts more smoothly and stay clean longer than others with plastic wheels. Their needle-point axles roll with a minimum of friction, so your locomotives can pull more cars. And non-magnetic materials prevent the false uncoupling of trains passing over uncoupling magnets. Kadee trucks are not only highly detailed, they're fully sprung and equalized as well, which means you'll get the ultimate in track-hugging operation. Kadee no. 500.
The Bettendorf Double Truss Truck was introduced in the 1930's by U.S. railroads and was allowed to be used in interchange service through 1993. The Kadee® #500, #502 & #550 represent 50- ton trucks for 100,000 pound cars.
