A.A.R. CODE FOR DESIGNATING DESIGN FEATURES FOR SIDE FRAMES AND TRUCK BOLSTERS HAVING BUILT-IN SNUBBING DEVICES SINGLE SHOE BRAKES
Association of American Railroads Operation and Maintenance Department Mechanical Division
The A.A.R. Code for designating design features for side frames and truck bolsters, having built in snubbing devices and single shoe brakes, was devised for simplification and standardization purposes. One of the greatest losses to the railroad industry is the unneces-
sary delay in returning to service foreign cars awaiting receipt of side frames or truck bolsters from owner roads. Castings marked with A.A.R. Code Numbers can be readily identified for interchangeability and proper substitutions can be made for rapid return of equipment to service.
Simplification of design reduces inventories and promotes greater interchangeability. Bolsters have been standardized for the dimension from spring seat to center plate for each truck design of the same nominal capacity and spring travel. Only bolsters having these standard dimensions will carry an A.A.R. Code Number. The light car coupler heights will vary due to difference in light car weights but will not exceed A.A.R. limits. All cars, when loaded to maximum rail load, will meet A.A.R. requirements for coupler heights. Standardization of the dimension from spring seat to center plate simplifies the problem of providing proper bolsters when cars in interchange service require bolster replacement.
