The class E-1 consisted of 25 0-8-0 Camelback switchers built by ALCO-Schenectady between 1912 and 1918. For burning fine anthracite, they had a large grate of 91.6 square feet. The Wootten firebox had a surface of 202 square feet, with additional 18 square feet in a combustion chamber. They were also designated 8S53 due to their eight wheels and 53,000 pounds of tractive effort. The superheated class E-2s had the same designation. The E-1 was retired between 1948 and 1954.
