A turbogenerator is the combination of a turbine directly connected to an electric generator for the generation of electric power. Large steam-powered turbo generators provide the majority of the world’s electricity and are also used by steam-powered turbo-electric ships.

A steam-powered turbogenerator (sometimes called a “dynamo”) supplied electricity for the headlight and for the classification lights, illuminated number boxes, cab and gauge lights, and tender lights in a steam locomotive. The generator is usually on top of the boiler or on its shoulder.
