This report, Volume I, provides a summary of the systems engineering study under taken as Phase I of a proposed five-phase program. The intent of the overall program is the development, in-service demonstration, and ultimate deployment of dual-mode locomotives. This study has confirmed the technical viability of the dual-mode locomotive (DML) based on a modified model SD40-2, which can operate from either a high voltage catenary electrified at 60 Hz or from an onboard diesel engine. The DML is available in both 50- and 25-kv versions and can have a regenerative electric brake capability if required. The weight of a 50-kv, regenerative DML (the heaviest option) is under 398,000 lb, with normal options included. The space requirements for the electric components are compatible with installation on existing locomotive platforms without interfering with the diesel power equipment. The cost of the conversion of an SD40-2 to the DML configuration at locomotive rebuild is up to $414,097.
