Pere Marquette 1225 is a 2-8-4 (Berkshire) steam locomotive built for Pere Marquette Railroad (PM) by Lima Locomotive Works in Lima, Ohio. 1225 is one of only two surviving Pere Marquette 2-8-4 type locomotives and it is the only example in operable condition. PM used 1225 in regular service from the locomotive's construction in 1941 until the railroad was merged into Chesapeake and Ohio Railway (C&O) in 1947; it remained in use on C&O's Michigan lines until 1951. In 1971, efforts began to restore 1225 to operation, an effort that culminated in its first excursion run in 1988. 1225's blueprints were used as the prototype for the locomotive image and its sounds were used in the 2004 film The Polar Express. The locomotive, listed on the National Register of Historic Places, is now used on excursion trains over the Tuscola and Saginaw Bay Railway.
