A hybrid locomotive is a type of train that combines two power sources, typically a traditional diesel engine and an electric motor. This design allows the locomotive to operate more efficiently by using electricity for low-speed operations and diesel power for higher speeds. The electric component can be powered by batteries or overhead lines, reducing fuel consumption and emissions. These locomotives are increasingly popular in the rail industry as they help to lower operational costs and environmental impact. By utilizing both diesel and electric power, hybrid locomotives can adapt to various rail conditions and improve overall performance while contributing to sustainability efforts.
