GP22ECO

The GP22ECO is a locomotive built from recycled GP40/GP40-2 parts. The frame, trucks, and carbody are refurbished, while the 16-645 engine is replaced with a new 8-710-ECO engine. The electrical system is replaced with a modern microprocessor-based system. Horsepower is reduced to 2,150 due to the smaller engine.
