Following extensive planning, construction of Washington's Metrorail transit system started in 1969. Seven years later, revenue service began on a 7-kilometre line section with five stations in operation. Another 25 years later, in 2001, the originally planned Washington Metrorail system, shown in Figure 1, was completed, reaching a total of 166 kilometres with 83 stations.flash_audioEngineeringSystems EngineeringTransportation EngineeringArticle
