506 Carlton

The Carlton line runs from the eastern terminus of Main Street Station (on Line 2 Bloor–Danforth), initially heading south on Main Street to Gerrard Street East. It then turns west onto Gerrard Street East and runs to Parliament Street where it turns north to Carlton Street. The streetcar goes west on Carlton Street, which at Yonge Street continues onto College Street. There, it passes College station on subway Line 1 Yonge–University. Continuing west, it passes Queen's Park station again on Line 1 Yonge–University. The route makes its way to the end of College Street at Dundas Street West. It then runs west on Dundas Street West to Howard Park Avenue, which it follows into its western terminus in High Park.

Some eastbound Carlton streetcars may short turn at Coxwell Avenue, and head southbound to loop at Queen Street East and Coxwell Avenue.

Streetcar service is provided 24 hours per day on most portions of the route. The late night trips operate as the 306 Carlton, which runs along the same route from the eastern terminus of Main Street Station to Dundas Street West. From there, it continues west along Dundas Street West to Dundas West Station, skipping Howard Park Avenue.

There were several versions of the Carlton route starting from August 1886 when the Toronto Street Railway created a horsecar line of that name. All versions traveled along Carlton Street but had a variety of terminals, and none of the earlier versions of the route had the east-west breadth of today's route.[6]

By July 1, 1923, the Carlton route had evolved to resemble today's 506 Carlton route. There were three differences between the 1923 route and today's route. In 1923, College Street terminated at Lansdowne Avenue; thus, the tracks for the Carlton route needed to turn south for one short block on Lansdowne Avenue to join the tracks on Dundas Street West. At Yonge Street, Carlton and College streets were not continuous as they are today; thus, Carlton streetcars had to do a right/left jog for one block using Yonge Street. At the east end of the line, there was no loop at Main Street north of Danforth Avenue in 1923; thus, Carlton streetcars had to turn east on Danforth Avenue to terminate at the Luttrell Loop at the corner of Luttrell Avenue and Danforth Avenue.[6][7]

On June 3, 1931, the jog at Yonge Street was eliminated by realigning Carlton Street to flow into College Street. On May 9, 1940, the jog at Lansdowne Avenue was eliminated by extending College Street to directly join Dundas Street West. On May 15, 1955, a loop was constructed at the site of today's Main station, thus providing relief from streetcar congestion at the Luttrell Loop, also used by the now-defunct Bloor streetcar line. Thus, by the third change, the Carlton route matched today's 506 Carlton route.[6]

On January 8, 1939, PCC streetcars were introduced on the Carlton route on Sundays, displacing Peter Witt streetcars.[8]^:42

Between April 25 and June 13, 1966, the loop at Main Station was constructed on the site of the 1955 loop. Carlton streetcars started using the new loop before the subway platforms were open to the public on May 10, 1968. During construction, Carlton streetcars had to be diverted to the Luttrell Loop.[6][9]

From February 18 to September 2, 2018, streetcars along the 506 Carlton route were replaced by buses due to a streetcar shortage[10] and to accommodate several construction projects.[11] [12]

By November 24, 2019, CLRVs were no longer being scheduled for 506 Carlton, having been replaced by Flexity Outlook streetcars, thus making the route fully accessible.[13][14]
