Conceptual 2100 Horsepower GenSet Switcher Locomotive. It uses 3 separate diesel gensets to power the unit as needed. When full power is not needed, the un-needed engine/s shut down. When more power is required, as many units as needed will automatically restart. This is the new trend for switch engines that may idle for long periods of time and typically do not need full power capability all the time.
I redesigned woody's cab, hood, carbody, and trucks from his SD40 and installed inelt-web's deere generator sets. A few more details to add, but mostly done.
