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 ~n 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 1.S only available overseas) and ~s economically attractive, the top line modification cost being $217,500.

The conclusion reached is that, by careful attention to detail, the concept of the dual-mode locomotive' is tech nically feasible. An attempt has been made to reduce the cost of the modifica tion by uti! izing as many existing components as possible without modification. Where modifications are necessary they have been kept as simple as possible. The 5040 and SD40-2 locomotives, on whi c h the conversion 15 based, are among the most rei iable locomotives of their type and care was taken not to impact the diesel mode operation. Full uti I ization of the traction motor within its pub! ished current, voltage, and power I imitations results in a higher powered locomotive in the electric mode. Therefore, if the steepest grades are traversed in .the electric mode, above base speed (all railroads contacted provide sufficient power to negotiate all grades above base speed, even for drag operations) a saving in locomotives results. vii viii SECTION 1 INTRODUCTION The purpose of this study was to confirm the technical feaslbl I ity of the dual-mode locomotive (DML) fol lowing Its Identification In the Wayside Energy Storage Study Final Report. That study showed that the DML could be used to enhance the existing rai I road operation and by and large made use of :8xisting equipment. PROGRAM OUTLINE The specific task which was added to the Wayside Energy Storage Study statement of work cal led for the fol lowing: . ' Item 4 - Locomotives - add the fol lowing Paragraph b. b. Conduct a prel imlnary study of the Dual-Mode Locomotive that wI I I inc Iude the fo I low ing: Determine the extent of modifications necessary. Develop prel iminary specifications for new components. Define control requirements. Identify locomotive structural modifications. Prepare prel iminary layouts. " PROGRAM METHODOLOGY The basic concept of the DML previously identified was re-examined to determine whether a more cost-effective. and technically acceptable version existed. The original concept did not take into account the intention of the Association of American Rai Iroads (AAR) to develop the "clean cab", positioning much of the equipment now located In the cab, in the short front hood.
