Wabtec Cardwell Westinghouse R-660398 Cylinder

R-660398 is an 8-inch TMX brake cylinder assembly from Cardwell Westinghouse (a Wabtec brand), remanufactured for use in railcar brake systems. Identified by part number 660398, this unit is deployed in AITX Railcar Recon programs to restore braking capability on legacy TMX-equipped cars without replacing the entire brake package. As a standalone cylinder within the TMX kit ecosystem, it interfaces with standard TMX mounting patterns and end connections used by Cardwell Westinghouse TMX components, and is referenced in Wabtec TMX literature as a brake cylinder assembly. The remanufactured designation differentiates it from new production cylinders while retaining compatibility with TMX system interfaces and the mechanical actuation path that translates piston movement into brake rig action. This item is suitable for railcars configured for TMX braking where an 8-inch diameter cylinder is specified, and it is commonly used by railcar repair and leasing networks that rely on remanufactured TMX components to extend equipment life.
