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 50kV catenary. The study concluded that the concept is technically viable and is economically attractive the top lime modification cost being $217,500.
