Dual-Mode Locomotive Systems Engineering. Volume 2: Detailed Description and Analysis

摘要

This report, Volume II, provides a detailed description of the analysis of the dual mode locomotive (DML) systems engineering study undertaken as Phase I of a proposed five-phase program. The intent of the overall DML program is the development, in-service demonstration, and ultimate deployment of dual-mode locomotives. This study has confirmed the technical viability of the DML based on a modified diesel-electronic locomotive model SD40-2, which can operate from either a high voltage catenary electrified at 60 Hz or from an onboard diesel engine. The DML can be made available in either 50- or 25-kv versions and could 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.
