Metro employs 2,716 full-time and part-time operators and operates 1,540 buses. King County Metro formally began operations on January 1, 1973, but can trace its roots to the Seattle Transit System, founded in 1939, and Overlake Transit Service, a private operator founded in 1927 to serve the Eastside. Metro is also contracted to operate and maintain Sound Transit's Central Link light rail line and eight of the agency's Sound Transit Express bus routes along with the Seattle Streetcar lines owned by the City of Seattle. Metro's services include electric trolleybuses in Seattle, RapidRide enhanced buses on six lines, commuter routes along the regional freeway system, dial-a-ride routes, paratransit services, and overnight “owl” bus routes. History A horse-drawn streetcar rail system debuted in Seattle in 1884 as the Seattle Street Railway. In 1918, the city of Seattle bought many parts of the Seattle Street Railway, on terms which left the transit operation in financial trouble.
