Originally built for export to Russia, the deal was cancelled with
the outbreak of WWII. Domestic railroads South Shore, and
the Milwaukee Road purchased these electric locos they called
“Little Joe” after Jos. Stalin didn’t get them. The Milwaukee Road
used these in the electrified portion of their ‘Lines West’ to assist long freight trains over the Idaho mountains.
