Appearing Fall/Winter 2010, R&LHS honors one of its own: John H. White Jr. is the dean of railroad historians, former transportation curator at the Smithsonian Institution, author of several authoritative reference works, and former editor of Railroad History. We’ll trace his career, and we’ll tell you why all of us are in his debt. We’ll also mark the retirement of America’s last interlocking tower and present two other stories on the development of train control technologies. And we venture beyond America’s borders – to Canada and Tibet, in search of railroading old and new.
