A cooling system for a hydrogen hybrid locomotive having a set of electric traction motors and a hydrogen fuel cell system for providing electric power for driving the traction motors includes a radiator for extracting heat from cooling fluid circulated through the hydrogen fuel cell system by a circulation system. The circulation system includes a bypass valve for bypassing a selected amount of the cooling fluid around the radiator and a radiator output valve for controlling an amount of the cooling fluid passed to the hydrogen fuel cell system from the radiator. A fan system provides air flow across the radiator. A control system selectively sets a position of the radiator output valve and a position of the bypass valve and selectively controls a speed of the fan, as required to control cooling of the hydrogen fuel cell system.
