The Santa Susana Depot in Simi Valley, California is the perfect stop for train aficionados of all ages. The quaint, little museum offers a glimpse into train stations of the last century back when the telegraph alerted engineers of the next trains entering the station. The museum also features a miniature train set built by hobbyists who can tell you the history of California through trains. Be sure to stay to watch as today's modern trains speed by just a few feet from the station's platform at more than 100 mph.
