Official Web site of King County Metro.
In 1973, Metro became responsible for all public transportation in the Seattle/King County area, acquiring the city owned Seattle Transit System, and the privately owned Metropolitan Transit Corporation serving the King County suburbs. Several companies originally developed horse car lines, cable car lines and electric street railway lines, which by 1901 had consolidated into Seattle Electric Co. In 1914, the city began operating some of its own streetcar lines, known as the Seattle Municipal Railway. And in 1919, the Seattle Municipal Railway acquired the Seattle Electric Co. system. In 1939, the system was reorganized as the Seattle Transit System. The last streetcars ran in 1941. And trolleybuses were introduced in 1939, and continue to operate.
Official Web site of Sound Transit, formed in 1997 to develop regional transit service in 3 area counties. Regional transit would connect King County with Snohomish County and the city of Everett to the north, and with Pierce County and the city of Tacoma to the south. Commuter rail service has been introduced, and a new light rail line has been opened.
Several individual streetcar companies were eventually consolidated into a single company, prior to the takeover by the city.
