Information
During the spring of 1930, the Great Northern Railway
received fourteen 4-8-4's from Baldwin Locomotive Works. Designated to their S2
class, they were numbered 2575 through 2588. Those assigned to the Great
Northern Railway’s Montana division operated between Williston, North Dakota and
Havre, Montana. Others operated on the Spokane division between Spokane and
Wenatchee, Washington. One Great Northern S2, number 2584, still survives and
is on display at the Havre, Montana depot. Photographs by Ben Ringnalda,
Great Northern Empire.
