Spokane Portland and Seattle Railway's E-1 class was a class of the only three 4-8-4 locomotives built by the Baldwin Locomotive Works in 1938. The E-1 class "Northerns" were very similar to the A-2 through the A-5 class "Northerns" on the Northern Pacific Railroad built by Baldwin from 1934–1943. Visually, the locos are near-identical. The only difference is that the Northern Pacific Railroad 4-8-4s burn coal and the 4-8-4s on the Spokane, Portland and Seattle Railroad burn oil (and have a longer, wider range as a result).
