ABSTRACT:
An apparatus for treating compressed air from a rail yard compressed air supply pipeline leading from a central air compressor to outlets at remote locations in a rail yard prior to charging air brake lines of trains with compressed air from the pipeline to prevent contaminants such as moisture, entrained atomized oil and/or particulates such as rust from getting into the air brake line of the train. The apparatus includes an air line, an air inlet connector at one end of the air line, an outlet connector at the other end of the air line, and at least one separator device interposed in the air line between the inlet connector and the outlet connector for separating contaminants from a stream of compressed air passing through the apparatus. A test apparatus for testing compressed air for oil contamination and a method of preventing contamination of an air brake line of a train with contaminants from a rail yard compressed air supply pipeline used to charge the air brake lines of trains at remote locations in a rail yard with air from a central compressor system is also disclosed.
