In his new book, "Michigan's Historic Railroad Stations", Detroit News art writer Michael H. Hodges photographs and profiles 31 depots across the state, from Detroit to Three Oaks to Iron Mountain. In this lecture and slideshow, Hodges traces the evolution of the train station and the styles architects employed to both tame and exalt rail transportation. Touching on news accounts, literature and film, Hodges also considers the central role depots once played as the nation's principal crossroads - a much-used, much-loved public space that has no real analog in American life today.
