ABSTRACT: This is the fourth volume of a four volume report entitled the Wayside Energy Storage Study, which comprises the following volumes: Volume I-Summary; Volume II-Detailed Description of Analysis; Volume III-Engineering Economics Analysis:Data and Results; Volume IV-Dual-Mode Locomotive: Preliminary Design Study. A preliminary design study was conducted to confirm the technical viability and economic attractiveness of the dual-mode locomotive concept based on the most common U.S. road locomotive, the SD40-2. The study examined the existing characteristics of the base locomotive and ensured that operation in the diesel mode would not be compromised by a locomotive which has a pantograph, transformer, converter, and choke added to permit operation from a 50 kV catenary. The study concluded that the concept is technically viable (although some equipment is only available overseas) and ~s economically attractive, the top line modification cost being $217,500. Volume III is available in photocopy or microfiche from the National Technical Information Service, Springfield,VA 22161.
