TheEMD GP22ECOis a 2,150hp(1,600 kW)B-Bdiesel-electric locomotiverebuilt byElectro-Motive DieselandNorfolk Southern's Juniata Shops. Initially EMD built two GP22ECO demonstrators, one based on aGP9and one based on aGP40,[1]but thus far all orders have been for conversions based onEMD GP40andEMD GP40-2series locomotives. The rebuild involves replacing the existingprime moverwith anEPATier-II-compliantturbochargedV8710G3A,withElectronic fuel injection.The prime mover is mated to an AR10 alternator for traction power, a CA6 alternator for control power, and a computerized control system. Applying this to a 6-axle locomotive results in aSD22ECO.Some 6-axle locomotives could alternately be converted into aSD32ECO,using a 3,150hp(2,350 kW)V12instead.
When applied to GP40 or GP40-2 series locomotives, this conversion does not alter the external appearance of the locomotive, although the conversion of the GP9-based demonstrator required extensive changes to the long hood. The GP22ECO offers customers a 'factory' upgrade of existing locomotives.
Norfolk Southern's units were rebuilt from GP38AC units. They also feature electrical, mechanical, and emissions improvements.
