Norfolk and Western 433 is a preserved class M 4-8-0 "Mastodon" type steam locomotive built by the American Locomotive Company's Richmond Locomotive Works in January 1907 for the Norfolk and Western Railway. It was one of 125 M Class engines in operation on the N&W for around 50 years. After surviving an accident in 1951, the 433 was rebuilt and worked in Bristol, Virginia for a time where he was also assigned as a back up locomotive for the Abingdon Branch. This "Mollie" also worked as a switcher in Roanoke, Salem, and Radford. The 433 was eventually retired in 1958 and it became one of only two M Class locomotives to survive aside from the "Lost Engines of Roanoke". It was cosmetically restored in 2002 and now resides as a static display along the old Virginia Creeper Trail in Abingdon.
