A.S.F.® Ride Control® 50 Ton Trucks Metal Fully Sprung Equalized Trucks 1pr. Mounts with a #2 or 2-56 screw. Mounting Screws not Included. The A. S. F.® A-3 Ride Control® 50-ton freight truck was introduced in the 1940’s 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 lateral 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 for modeling the transition era up to 1994 when friction bearings were no longer allowed in interchange service.
