Great Northern 2507 is a 4-8-2 "Mountain" type steam locomotive, a member of the P-2 class. Built for passenger service, the locomotive was assigned to pull the Great Northern's mainline passenger trains such as the Empire Builder and Oriental Limited, until being retired in December 1957 and sold to Spokane, Portland and Seattle Railway. GN 2507 is one of only two surviving examples of a P-2 class locomotive and, since 2003, has been on display at Wishram station in Wishram, Washington.
