#563 Self-Centering A.S.F.® A-3 Ride-Control® Truck
with 33" ribbed back wheels 1 Pair

The A. S. Foundries® 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.
