SP&S Class E-1

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 & Seattle Railroad burn oil (and have a longer, wider range as a result).

Preservation

There is only one survivor, and it is the first of the class built. #700, which was restored by, and is maintained by, the Pacific Railroad Preservation Association. #701 and #702 were both scrapped after they were retired. Since mid-2012, since #700 Back-Strikes, [1] it resides at the Oregon Rail Heritage Center, in Portland, where the public can view it during the center's opening days.[2] It is taken on special trips once or twice a year.
