Beskrivning på engelska: 50-ton Freight Truck 33" smooth back wheels. ASF (American Steel Foundries) A-3 Ride Control 50-Ton Freight Truck was introduced in the 1940s and is one of the forerunners of modern freight trucks. Features embodied into this design include a longer spring travel, no spring planks and constant friction control using friction castings in the bolster to dampen excessive laternal roll of the car. These design features allowed for a higher train speed with less danger of derailment than previous designs. ASF sold over 140,000 sets by 1949. This truck is excellent fo modeling the transition era up to 1994 when friction bearings were no longer allowed in interchange service. Kadee® freight trucks feature: Non-magnetic wheels, insulated needlepoint axles, highly flexible sprung trucks with metal sideframes and bolsters. 1 par boggier/förpackning. Utgår ur sortimentet.
