Sugar Pine Lumber Company 4, (SPL 4) Later known as PALCO 37, W&C 37, and WWRR 37, is a 2-8-2ST "Mikado" built by the American Locomotive Company in 1925. After the Sugar Pine Lumber Company went bankrupt in 1933, it wound later be purchased by Pacific Lumber Company and renumbered to 37. The engine was briefly purchased to railfan Frank Bayliss before starting its heritage railroad career on the Wawa & Concord Ville Railroad in 1966.[1] The engine saw service on the Wilmington & Western Railroad before being retired in 1990. In 2003, the Timber Heritage Association purchased the locomotive and had her stored at the Strasburg Railroad starting in 2010 with intentions of operational restoration.[2] In 2023 the Timber Heritage Association sold the engine to the Age of Steam Roundhouse where as of 2024 she is now on display.[3][4]
