EMD SD32ECO
Encyclopedia
The EMD SD32ECO is a 3150 hp 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.
At least 8 Union Pacific SD60Ms have been 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.
The external appearance of the converted locomotive is altered by application of the "flared" radiators of the SD70 Tier-II. The recently converted locomotives (including the 9905 and 9906, seen recently at the CSRM; the 9901 and 9908 also) have also had the distinctive SD70 Tier-II-type fuel tanks applied.

EMD 710
The EMD 710 is a line of diesel engines built by Electro-Motive Diesel . The 710 series largely replaced the earlier EMD 645 series. The EMD 710 is a large two-stroke diesel engine that has a displacement per cylinder. Since its introduction, EMD has continually upgraded the 710G diesel engine...
V16
V16 engine
A V16 engine is a V engine with 16 cylinders. Engines of this number of cylinders are uncommon in automotive use.A V16 engine is perfectly balanced regardless of the V angle without requiring counter-rotating balancing shafts which are necessary to balance Straight-4 and odd number of cylinder...
prime mover
Prime mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. The term is generally used when discussing any locomotive powered by an internal combustion engine...
