Pere Marquette 1225 is a class "N-1" 2-8-4 "Berkshire" type steam locomotive built in October 1941 for the Pere Marquette Railway (PM) by Lima Locomotive Works (LLW) in Lima, Ohio. No. 1225 is one of two surviving Pere Marquette 2-8-4 locomotives, the other being 1223, which is on display at the Tri-Cities Historical Society near the ex-Grand Trunk Western (GTW) coaling tower in Grand Haven, Michigan. It is perhaps most famous for serving as the basis for the locomotive in the 2004 film, The Polar Express.
