ES-2 drawing.

The Milwaukee Road's class ES-2 comprised four electric switcher locomotives . Two were built in 1916 and the final two in 1919. They were of steeplecab design, with a single roof-mounted pantograph to access the Milwaukee's 3,000 V DC overhead line. Originally numbered 10050–10053, they were renumbered E80–E83 in March 1939. The E80 was the Deer Lodge, Montana switcher.
