Train arrival: Cleveland Park stop on the Red Line, DC Metro, 2009

Although there are only two lone people awaiting the arriving train, the nation's capital's high-speed mass-transit system set an all-time ridership record on January 20, 2009 for the inauguration of the 44th president of the United States: Barack Obama. The passenger count that cold winter day was more than 1.12 Million people. Staggering.
