L. Whitlock Office Engineer the Denver (Col.) Tramway ANEW type of special work which represents a rad-ical departure from the standard construction ofthe Denver Tramway was recently installed at a down-town intersection in Denver. This layout, shown inthe accompanying illustration, has been termed theoutside switch.
