System
Since opening in 1976, the Metro network has grown to include six lines, 91 stations, and 118 miles (190 km) of route.[37] The rail network is designed according to a spoke-hub distribution paradigm, with rail lines running between downtown Washington and its nearby suburbs. The system makes extensive use of interlining – running more than one service on the same track. There are six operating lines.[37][38] The system's iconic official map was designed by noted graphic designer Lance Wyman[39] and Bill Cannan while they were partners in the design firm of Wyman & Cannan in New York City.[40]About 50 miles (80 km) of Metro's track is underground, as are 47 of the 91 stations. Track runs underground mostly within the District and high-density suburbs. Surface track accounts for about 46 miles (74 km) of the total, and aerial track makes up 9 miles (14 km).[37] The system operates on a unique track gauge of 4 ft 8 1⁄4 in (1,429 mm).[why?]
In an effort to gain revenues, WMATA has started to allow retail ventures in Metro stations. WMATA has authorized DVD-rental vending machines and ticket booths for the Old Town Trolley Tours and is seeking additional retail tenants.[41]
