The EMD SD32ECO is a 3,150 hp (2,350 kW) C-C diesel-electric locomotive rebuilt by Electro-Motive Diesel. It is primarily the application of a conversion kit to an existing EMD SD60-type locomotive. This involves replacing the existing 710G3A V16 prime mover with an EPA Tier-II-compliant 710G3B-T2 turbocharged V12 engine, with electronic fuel injection. Many of the donor SD60's major components and subsystems are recycled, and are recertified as equal to new. However, the locomotive's control system is all new.
