The Washington Metropolitan Area Transit Authority closed the Smithsonian, L’Enfant Plaza, Federal Center SW, and Capitol South subway stations for construction work on tracks and station platforms this past weekend. Metro buses were used to bridge the rail line gaps. Since subway trains can haul 1,000 to 1,400 passengers and a bus fits only about 75, it took lots of buses. The logistics reminded us of the Berlin Airlift (June 27, 1948 to May 12, 1949) when British and U.S. airplanes flew food and coal into West Berlin, which had been blockaded by the Soviets.
