Editing EMD SD60 (section)

==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 [[EMD SD40-2|SD40-2]].

===SD60F===
The SD60F was ordered and was operated by [[Canadian National]] and has a full-width [[Cowl unit|cowl body]] and crashworthy "safety cab" with a four-piece windshield. CN retired the SD60F in 2017, however a handful were sold off and are still working on two shortlines in North Dakota. [[Dakota, Missouri Valley and Western Railroad]] has six, and the [[Northern Plains Railroad]] has five. 14 units are currently on the [[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. They are easily distinguished from the SD60M by the visible vertical seam just behind the front of the nose. The same cab was later used on EMD's [[EMD SD70I|SD70I]], [[EMD SD75I|SD75I]], [[EMD SD80MAC|SD80MAC]] and [[EMD SD90MAC|SD90MAC]] locomotives. Only [[Conrail]] ordered this model, and after 1999 all were split between the [[Norfolk Southern]] and [[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 [[short hood]]. Early models until 1990 featured a three-piece windshield with vertical windows (nicknamed "triclops"), identical to the windshields found on EMD's [[EMD SD40-2F|SD40-2F]] and [[EMD F59PH|F59PH]] models. Later production from 1991 used two windshield panes that were sloped back, and had a somewhat shorter nose tapered on the sides. Purchasers of this model included Conrail, [[Union Pacific]], [[Burlington Northern]] and the [[Soo Line Railroad]]. Conrail's orders were split between the Norfolk Southern and CSX upon their acquisitions of parts Conrail 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 [[alternating current]] traction motors. Although four demonstrator SD60MAC units tested on the [[Burlington Northern]] proved the viability of EMD's AC traction system, all subsequent orders were for the [[EMD SD70MAC|SD70MAC]] locomotive.

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&nbsp;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.<ref>{{cite web|url=http://www.altoonaworks.info/rebuilds/ns_sd60e.html |title=NS SD60E Rebuilds |publisher=AltoonaWorks.info |access-date=2012-09-09}}</ref>
