- 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.
