The EMD SD22ECO is a 2,150 hp (1,600 kW) C-C diesel-electric locomotive rebuilt by Electro-Motive Diesel. It is, along with the GP22ECO, primarily the application of a conversion kit to an existing EMD SD40-type locomotive. This involves replacing the existing prime mover with an EPA Tier-II-compliant turbocharged V8 710G3A-T2, with electronic 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.[1] This conversion does not alter the external appearance of the locomotive.
The Kansas City Southern Railway and Kansas City Southern de México were the only railroads to have rebuilt SD40s into SD22ECOs.[2] [3]
