If you are interested in either photography or railroads, this is a wonderful museum to visit. Start with the film in the far back theater which introduces you to both the photographer as well as the history of railroading. Then start going around each room, really reading the captions which explain the photos. Read about why he took his photos at night. Appreciate the patience and planning that went into each photograph. Learn the significance of the trains and the people that he selected to include in his collection.
