Chicago Lake Street Elevated No. 1 to 35

United States 1893 35 produced
“Clarence A” in 1893 PD

In 1893 and 1894, the Lake Street Elevated in Chicago got 35 0-4-4T Forneys from the Rhode Island Locomotive Works. They were the largest of their kind on any US elevated railroad and the first 25 were named after shareholders of the railroad, like “Clarence A” pictured. They were two-cylinder compounds with cylinder diameters of 13 and 21 inches. Despite their success, they were retired in 1896 when the Lake Street Elevated was electrified.

Locomotives 16 to 32 and 35 were sold to the Long Island Rail Road. Most of the rest went to logging companies, others got new owners in the industry. No. 35 was rebuilt to a 2-4-4T in 1898 and soon also simpled. In 1908 it went to the Morristown & Erie and became their No. 2. In 1922 it was sold again to the Hanover Brick Co. where it was used until its scrapping in 1936.
