| Abstract | The Federal Railroad Administration (FRA) funded a project conducted by Transportation Technology Center, Inc.’s (TTCI) Association of American Railroads’ (AAR) Natural Gas Fuel Tender (NGFT) Technical Advisory Group (TAG) in developing industry standards for NGFT tenders. The objective was to measure and understand the triaxial displacement environment that interconnections (e.g., gas, cooling system loop, electrical, air, etc.) between the locomotive and adjacent tender vehicle will face during normal full-scale freight train operations in revenue service. The worst-case scenario of a displacement environment between a common line-haul locomotive and a trailing vehicle (i.e., simulating a fuel tender) were documented. This included measuring and understanding the dynamic environment where equipment passing natural gas (NG) between the locomotive and tender will be required to survive in mainline train operations. The NGFT TAG analyzed the data gathered in the development of specification requirements for NG tender fuel transfer components (e.g., hoses, wires and connectors for gas/heat exchange fluids/electrical power/control), and testing of such components. Additionally, this report describes the measurement of relative longitudinal, lateral and vertical displacements and accelerations between the locomotive and simulated fuel tender. |
