Diesel Era is compiling images and information on The Milwaukee Road’s (MILW) GP40 diesel locomotive fleet for a future survey of these four-axle units. The road’s GP40s came in several batches (from 1966 to 1969) and with renumbering and other factors impacting the collection of 3,000-hp road units. If you have information and/or images that can contribute the documenting this group of Milwaukee Road motive power, please send an email with details. You can reach Diesel Era‘s editor under the “Contact Us” tab above.
