The EMD SD60 is a 3,800 horsepower (2,800 kW), six-axle
diesel-electric locomotive built by General Motors Electro-Motive Division
, intended for heavy-duty drag freight or medium-speed freight service. It was introduced in 1984, and production ran until 1995.
History and development
The SD60 is essentially identical to the
Chicago & North Western's railroad manual estimated that the SD60 is 3% more fuel efficient than one SD50, while a pair of SD60s was up to 16% more efficient than three SD40s pulling a standard coal train.[1]
Norfolk Southern has been modernizing their old SD60s since 2010 into SD60Es, a model specific to NS.[2]
Models
Several variants of the SD60 were built, including:
SD60
This was the original model, and had a conventional hood unit configuration with the 40 Series (spartan) cab first employed on the SD40-2.
SD60F
The SD60F was ordered and was operated by
Aberdeen, Carolina & Western Railway in North Carolina
.
SD60I
The SD60I model has a full-width short hood and features the so-called "WhisperCab" that was insulated from sound and vibration using a system of rubber gaskets. The same cab was later used on EMD's
CSX
. All SD60i locomotives have either have been scrapped, sold to new owners or retired.
SD60M
The SD60M features a "North American safety cab" design and has a full-width
Burlington Northern and the Soo Line Railroad
. Conrail orders were split between the Norfolk Southern and CSX back in 1999. All Norfolk Southern and CSX SD60M locomotives have either been scrapped, sold to new owners, or retired.
SD60MAC
The SD60MAC is similar to the SD60M but is equipped with
SD70MAC
locomotive.

SD60E
The SD60E is a custom rebuild of standard cab SD60 for Norfolk Southern created at the
Juniata Shops with the prototype being delivered in 2010 and the majority of the production taking place between 2013 and 2017. The SD60E utilizes a new NS-designed wide nose cab with increased crash protection, new electronics and up-rating the engine to the 4000 hp 710G3B standard. Norfolk Southern bought additional SD60s from Helm Leasing specifically for the SD60E program with the aim to eventually rebuild 240 SD60s, however the project was terminated after 135 had been completed and Norfolk Southern's remaining inventory of unrebuilt SD60, SD60M and SD60I locomotives were subsequently sold or scrapped in 2019. In May 2021, Norfolk Southern regeared SD60E numbers 7034 and 7035 to go 79mph and assigned the locomotives to the railroad's Office Car Special train.[3]
