Images of Rail: Pere Marquette 1225 presents the history of steam locomotive 1225, one of 39 Berkshire Class 2-8-4's built between 1937 and 1944 for the Pere Marquette Railway. Although it is best known for being the sound and image behind the movie adaptation of Chris Van Allsburg's The Polar Express, 1225 has a rich history that preceded a life as a movie star. From her construction at Lima Locomotive Works and important role in hauling material from factories to the front in World War II to her unlikely preservation on Michigan State University's campus and eventual restoration, the history of 1225 covers nearly 75 years. The locomotive is now housed at the Steam Railroading Institute in Owosso, Michigan, and the story behind it will take readers back to a time when whistles in the night charged the imagination and the United States truly was the "Arsenal of Democracy."
