| Post subject: | Historic Single Car Test Codes |
Long overdue, but the compilation of historic single car test codes published by HRA predecessor TRAIN is now available on the HeritageRail Alliance website: https://heritagerail.org/wp-content/uploads/2025/08/Single-Car-Test-Codes-for-Historic-Valves.pdf. These are the codes needed if testing "historic" car equipment with an OEM manual device; that is, D-22 or older passenger valves, and K or older freight valves. These codes represent the latest revision for the respective valves/systems they cover. Note that the above compilation does not include the quarterly calibration test for the passenger device. For that (as directed in section 2.4 of the compilation) one must reference the APTA passenger single car test codes: https://www.apta.com/research-technical-resources/standards/passenger-rail-equipment-safety-standards/apta-pr-m-s-005-98/. The original 1998 version is the latest revision of the code and the quarterly test for the non-Flowrator device. Revision 4 is the latest revision of the code as a whole and covers the quarterly test for the Flowrator equipped device. (Aside from the quarterly device tests, note that the APTA code is applicable to 26-C or equivalent equipment, only.) The historic codes are also available individually on the APTA website. - Erich Armpriester Strasburg Rail Road Mechanical Services |

Are these single car test codes also applicable to the non-OEM devices made from pipe fittings and commercial valves? |

Jeff, No, they are not applicable to the non-OEM pipe fitting device. HRA RP-002 was published with the intent of being directly applicable to this device, thereby eliminating any "translation" that might need to be done on the part of the operator if attempting to pair the pipe fitting device with an OEM code. That is, however, with the one exception being the brake cylinder and retaining valve (if used) leakage tests. As the exact construction and operation of the device does not factor into these leakage tests they were not included in RP-002, and as such an operator must reference the OEM code to carry out these tests. - Erich Armpriester |
