    摘要: In one embodiment, a multi-engine locomotive includes at least one converter to convert mechanical energy outputted by the engines to Direct Current (DC) electrical energy, a traction motor, and a DC bus connected to the engines, converter, and traction motor. The engines are configured to provide a power-per-length and/or power density that is greater than the power-per-length and/or power density of a single-engine locomotive having a power rating approximately the same as the cumulative power rating of the engines in the multi-engine locomotive.
