Career

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, 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.

Owners

At least 24 Union Pacific SD60Ms have been scheduled to be sent to EMD for this rebuild and a number have been returned by EMD and are already in revenue service. So far, all converted locomotives have been of the later "two window" cab type, not the earlier "three-window" cab type. SD59MX is the Union Pacific designation for this type.

BNSF has sent 3 SD45-2 locomotives to be rebuilt as SD32ECOs. Unlike UP's SD59MX, BNSF's SD32ECOs retain the appearance of an SD45-2. So far, 3 have been ordered, and will be numbered 1350-1352.

Appearance

The external appearance of the converted locomotive is altered by application of a flared radiator section, similar to the SD70M-2 and SD70ACe Tier-II, and very much like late model SD70M and SD70MAC locomotives in appearance. The recently converted locomotives (including UP 9905 and 9906, seen recently at the CSRM; and others up to at least UP 9923) have also had the distinctive SD70 safety fuel tanks applied.

Advertised benefits

Advertised benefits include:

EPA Tier-II compliance.
Fuel savings up to 25%.
Lube oil savings up to 50%.
Upgradeable software can be tuned for reduced emissions or improved fuel efficiency.
Microprocessor control offers diagnostics, wheel slip control, and optimal wheel/rail adhesion.
184-day maintenance cycle instead of 92-day.
15,000 MWh overhaul cycle.
Reduced maintenance expense due to use of standard 710 prime mover.
Automatic Engine Start Stop system keeps locomotive ready without wasting fuel.
