Toronto-gauge railways are streetcar and rapid transit lines built to Toronto gauge, a broad gauge of . This is wider than standard gauge of . The gauge is unique to the Greater Toronto Area and is currently used on the Toronto streetcar system and the three heavy-rail lines of the Toronto subway system, both operated by the Toronto Transit Commission. Several now-defunct interurban rail systems (called radial railways in southern Ontario) also once used this gauge. The Halton County Radial Railway, a transport museum is located on one of the former interurban lines and uses the Toronto gauge.
The unique gauge has remained to this day because it is easier to adapt new rail vehicles to fit the gauge than to convert the entire system to standard gauge. An alternate name for Toronto gauge is TTC gauge, named after the Toronto Transit Commission, the only operator currently using the gauge although the gauge existed prior to the creation of the TTC in 1921.
Streetcar usage
All TTC streetcar routes, both past and present, have used the Toronto gauge. The TTC had three predecessor companies that also used Toronto gauge, each with a network of streetcar lines within the City of Toronto: Toronto Street Railway (1861–1891) Toronto Railway Company (1891–1921) Toronto Civic Railways (1911–1921)
The Toronto Street Railway created the Toronto streetcar system opening its first horsecar line in 1861. It also created the broad Toronto gauge to allow horse-drawn wagons and carriages to use the inside of the rail for a smoother ride through muddy, unpaved streets. The gauge also had the effect of precluding the movement of standard-gauge freight cars along streetcar lines. When its franchise ended in 1891, the Toronto Railway Company (TRC) took over the system and replaced horse-drawn streetcars with electric trams; it continued the use of Toronto gauge. Because the TRC refused to service neighbouring areas annexed by the City of Toronto, the City created the Toronto Civic Railways (TCR) in 1911 to serve those areas. TCR lines, clustered in the west end, east end and mid-town, were not interconnected. To move streetcars between carhouses, the TCR used the tracks of the TRC, which is one reason that the City chose Toronto gauge for the TCR. The other reason is that when the TRC franchise ended in 1921, the City wanted to merge the two systems. There were no permanent links between the tracks of the TCR and TRC; temporary track was laid at night when the TCR needed to transfer streetcars. When the TRC franchise ended in 1921, the TTC acquired both the TRC and the TCR and amalgamated the two systems, permanently linking their tracks.
Explanations for the gauge Toronto gauge was first used for the horsecar system opened by the Toronto Street Railway in 1861. Two explanations are offered for the width of the gauge: The gauge would make it impossible for the steam railways to use city tracks, and The track would support the wheels of non-rail carriages and wagons, allowing such vehicles to handle muddy conditions that made roads impassable. According to transit advocate Steve Munro, "TTC gauge is English carriage gauge".
According to the TTC, advocating the first explanation, the City of Toronto feared that the street railway franchise operator would allow the operation of steam locomotives and freight trains through city streets, as was common practice in Hamilton, Ontario (until the 1950s) and in many US cities, such as New York City and Syracuse, New York.
However, fear of freight trains invading the streets was from the era of about 1891 to 1921, over 30 years after the creation of Toronto gauge, which makes it an unlikely reason for the Toronto gauge. During this era, railway entrepreneurs William Mackenzie and Donald Mann controlled the Canadian Northern Railway, the Toronto Railway Company plus several radial railway lines including the Toronto Suburban Railway. About 1912, the Toronto Suburban wanted to convert its system from Toronto gauge to standard gauge, but the City of Toronto obtained a court injunction blocking the re-gauging over fears of freight cars in the streets. The railway, however, prevailed and the system was converted to standard gauge in 1917.
Also, horsecar tracks could be of very light construction, adequate for horse-drawn trams, but unsuitable for heavier vehicles. When the Metropolitan Street Railway converted its streetcar line in North Toronto from horse to electric operation, the faster heavier electric trams damaged the horsecar rails, which required the line to be shut down and the track rebuilt to a higher standard.
In support of the second explanation, the 1861 agreement between the City of Toronto and the Toronto Street Railway stated:
As wagons were normally built at standard gauge, the streetcar rails were selected to be slightly wider, which allowed the wagons to ride on the inside sections of the rail and the streetcars on the outside. The Williams Omnibus Bus Line changed the gauge of its buses in 1861 to fit this gauge. At the time, track for horsecars was not the modern 'T' rail was but wide and flat, with a raised section on the outside of the rail.
Variations in Toronto gauge Before TTC ownership, however, the streetcar gauge was Old time trains Track gauge or , depending on the historical source, instead of today's .
When the Toronto Street Railway opened its first horse-drawn streetcar line in 1861, it used a variation of Toronto gauge, a width of . When the Toronto Railway Company took over the streetcar system in 1891, its charter stipulated a gauge of When the TTC took over streetcar operation in 1921, it set the Toronto gauge at the present day's width.
However, Ken Heard, Consultant Museologist, Canadian Museums Association, was reported to say: "One of the terms of these agreements was that the track gauge was to accommodate wagons. As horse car rail was step rail, the horse cars, equipped with iron wheels with flanges on the inside, ran on the outer, or upper step of the rail. Wagon wheels naturally did not have a flange. They were made of wood, with an iron tire. Wagons would use the inner, or lower step of the rail. The upper step of the rail guided the wagons on the track. In order to accommodate this arrangement, the track gauge had to be 4 feet, 11 inches. As the streets themselves were not paved, this arrangement permitted wagons carrying heavy loads a stable roadbed." In support of Heard's statement about the pre-TTC gauge, the Charter of the Toronto Railway Company said "the gauge of system (4 ft. 11 in.) is to be maintained on main lines and extensions thereof".
According to Raymond L. Kennedy said: "The street railways were built to the horse car gauge of 4 feet 10 and inches. (The TTC changed this to 4 and is still in use today even on the subway. )" James V. Salmon said the "city gauge was 4 ft ." Both these sources were describing a former streetcar junction at the intersection of Dundas and Keele Streets laid entirely to Toronto streetcar gauge until August 1912. The junction was used by both the Toronto Suburban Railway and the Toronto Railway Company.
Subway usage Heavy rail All three heavy-rail subway lines in Toronto use Toronto gauge. They are: Line 1 Yonge–University Line 2 Bloor–Danforth Line 4 Sheppard
Some early subway proposals involved using streetcars at least partially in tunnels so that using the same gauge would be advantageous, but the idea was ultimately dropped in favour of dedicated rapid transit trains. Nonetheless, the heavy-rail lines use the streetcar gauge today. According to rail historians John F. Bromley and Jack May, the reason that the Yonge subway line was built to the streetcar gauge (Toronto gauge) was that between 1954 and 1965, subway bogies were maintained at the Hillcrest Complex, where the streetcar gauge is used for shop tracks. The Davisville Carhouse was not equipped to perform such heavy maintenance, and the bogies would be loaded onto a specially built track trailer for shipment between Davisville and Hillcrest. This practice stopped with the opening of the shops at Greenwood Yard in 1965.
Using Toronto gauge for the Yonge subway line had secondary benefits. A number of ex-streetcar vehicles were used as work trains for the subway, taking advantage of the common gauge. Before the opening of the Yonge subway in 1954, there was also a temporary interchange track between the Yonge streetcar line and the Davisville Yard on the north side of the Belt Line bridge. In 1953, subway cars 5000 and 5001, after being displayed at the Canadian National Exhibition, were mounted on shop bogies and towed at night by a Peter Witt motor to the Davisville Yard via the Yonge streetcar line using the temporary interchange. (They arrived at the CNE from the Hillcrest Complex via the Bathurst streetcar line. Because of the subway car width, buses had to replace night streetcar service during the movements. At the CNE, the subway cars were displayed on their proper subway bogies.)
Standard-gauge lines In addition to the heavy rail lines, there were and will be light metro and light rail lines that are considered to be part of the Toronto subway system but use the that is the usual track gauge in Canada: Line 3 Scarborough was a light metro using Intermediate Capacity Transit System technology that is incompatible with running on heavy rail lines, thus making customization for Toronto gauge of no benefit. However, when its ICTS vehicles needed anything more than basic service (which can be carried out at the McCowan Yard), they were carried by truck to the Greenwood Subway Yard. Line 5 Eglinton and Line 6 Finch West are light-rail lines not customized to use Toronto gauge to ensure a better price for purchasing vehicles and to have a degree of commonality with similar projects within Ontario. The Ontario Line is an under-construction light metro line that will be a standalone line from the heavy rail lines and will use lighter and shorter driverless trains with automatic train control (ATC) manufactured by Hitachi Rail.
Hamilton In 2009, the City of Hamilton Public Works produced an analysis for a future light rail line in Hamilton. The analysis looked at whether the city should use standard gauge or "TTC gauge". The report said the benefit in using the Toronto gauge would be to save costs if Hamilton's order could be combined with Toronto's for light-rail vehicles, and to encourage their manufacture in the Greater Toronto Area. The benefit of standard gauge would be greater compatibility with other tram systems and the elimination of the costs to customize the bogies. This analysis occurred before Metrolinx took over the project and stipulated the use of standard gauge.
Radial railways Radial railways were Interurban tram lines serving communities just beyond the then-city limits. These interurban lines were called "radials" in southern Ontario as they radiated from a city. By the early twentieth century, there were two radial systems operating from the City of Toronto: Toronto and York Radial Railway Toronto Suburban Railway
Most of the radials within the above two systems used Toronto gauge at some time during their existence. The following sections give a highly abridged summary of each line, focusing mainly on the gauge used. Click on links for a more extensive history.
Toronto and York Radial Railway
By 1904, the T&YRR had acquired the following independent radial railways: Metropolitan Street Railway (Toronto): Metropolitan (later Lake Simcoe) line Toronto and Scarboro' Electric Railway, Light and Power Company: Scarboro line Toronto and Mimico Electric Railway and Light Company: Mimico (later Port Credit) line
In 1922, the City of Toronto acquired the assets of the T&YRR, and contracted with the Hydro-Electric Railways to operate the radial lines on behalf of the City. However, ridership declined and the City suffered operating losses.
