ABSTRACT: This report summarizes the methods and results of train noise measurement carried out on August 30, 2001 at the Transportation Test Center in Pueblo, Colorado. The measurements were performed by Harris Miller Miller & Hanson, Inc on behalf of the Federa lRialroad Administration, under subcontract to Parsons Transportation Group. The objective of the measurements was to obtain wayside noise data during the operation of the Ihgh-Speed Non-Electric Locomotive, a locomotive with a lightweight turbine engine that is less than one-tenth the size and approximately 38,000lb lighter than a traditional diesel engine. Data were obtained for various train speeds and operating conditions during controlled demonstration tests of the locomotive. These data are compared with similar data available for other fossil fuel locomotives.
