Canadian National 3377 is a preserved class "S-1-d" 2-8-2 "Mikado" type steam locomotive currently on display at the Steamtown National Historic Site in Scranton, Pennsylvania.

[1] It was later renumbered to 3377 and would spend the rest of its career operating on the Canadian National Railway.

[1] The locomotive was sold to the Edaville Railroad in September 1961, and then was later moved to Bellows Falls, Vermont and became part of the Steamtown, U.S.A.

3377 will possibly be the next candidate for restoration to operating condition, once the restoration of Boston and Maine 3713 is completed, due to sister locomotive No.
