A multi-engine locomotive configuration is disclosed wherein engine outputs to DC traction motors are controlled by connecting the alternators with rectifiers in series for each engine of a multi-engine locomotive. This configuration uses the minimum number of rectifying diodes, eliminates the need for chopper circuits and simplifies the method of controlling the sequencing and output of two or more engines. The approach, which reduces the parasitic power loss by reducing the number of diodes, also enables a simplified means to efficiently manage engine cooling without additional cost and complexity of electrically-driven radiator fans.
