Introduced in the 1940’s - Used in interchange service through 1994.

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 AAR truck is excellent for modeling the transition era up to 1994 when friction bearings were no longer allowed in interchange service.

Once Kadee trucks have been fitted to the car, always check the coupler height. Coupler height modification will probably be required due to non-standardized original equipment manufacturing in O-Scale. Always check coupler height and trip pin clearance using the #812 Kadee® Coupler Height Gauge for O-Scale, and check for the correct coupler height and trip pin clearance. If needed only use a Dry Graphite Lubricant such as our #231 “Greas-em” to lubricate the trucks couplers or moving parts.

Disclaimer: These instructions are guidelines for adapting Kadee® all metal 2-piece trucks to O-Scale rolling stock. Some additional modifications may be required and there is no express warranty that Kadee® trucks will work in all applications.
