Roger L. Titus is a noted rail-traction historian and postcard collector. He is the co-author of "Destinations," a LARHF-published title documenting the rise of Southern California through vintage postcards and their relationship to the trolley lines that fueled Southland growth. As a teenager, Roger and his father Robert rode the Pacific Electric and Los Angeles Railway systems, photographing the systems as they were on the verge of shutdown. His collection provides a brilliant snapshot into late-1940s through late-1950s Southern California, and how trolley systems defined our way of life.
