Toronto's streetcar system is one of the few in North America still operating along street-running tracks. It has been operating since the mid-19th century. Horsecar service started in 1861, and 600 V DC overhead electric service began in 1892. New TTC routes since the 1940s have generally been operated by other modes of transportation, and the less busy streetcar routes have also been converted. Streetcar routes are now focused on the downtown area, although two run farther from the core: one being on St. Clair Avenue, from Lake Ontario on average, served by the 512 St. Clair streetcar route, and another on Lake Shore Boulevard (the western portion of 501 Queen), which runs through the Etobicoke district nearly to the city limits with Mississauga at Etobicoke Creek.
