The E83 became surplus and was scrapped in 1952. The other three continued in service until the end of

In addition to the pantograph, the ES-2s were equipped with a wooden trolley pole which was spring-tensioned and manually-operated, in the same manner as on a trolley car, though it was never meant for use while in motion. Its sole purpose was to make stationary contact with the wire to charge an

Division eschewed electric switchers entirely, as its operating characteristics and economics were more favorable to otherwise underutilized steam (later diesel) switchers which also served the Milwaukee's non-electrified branches in the area.
