The Scarborough RT[2] ( also known as SRT or the RT and officially 3 Scarborough RT),[3] is a rapid transit line on the Toronto subway and RT system in Toronto, Ontario, Canada. The line is internally referred to as Route 3 (formerly route 603),[4] but this number is not used by the public or shown on TTC maps and signs.
Rather than the standard (and relatively large) Toronto Transit Commission subway cars used by the three other rapid-transit lines, it runs smaller, fully automated, medium-capacity rail transport system using Intermediate Capacity Transit System (ICTS) Mark I vehicles built by Urban Transportation Development Corporation (UTDC) and powered by linear induction motors. They are the same as those used successfully by the Vancouver SkyTrain and the Detroit People Mover. The TTC is the only system to operate them with a driver on board.
The line has six stations and is 6.4 km (4.0 mi) in length, 0.5 km (0.3 mi) of it underground. It is operated by the Toronto Transit Commission and administered as part of its subway system. The Scarborough RT differs from the city's other three lines in its use of linear induction motors, and automated operation . RT stands for "rapid transit", as the name "subway" seemed inappropriate for a line with only a small section underground. Internally, the TTC uses the name "rapid transit" to refer to all four lines. The term is also sometimes used for streetcar lines. Unlike those of the rest of Toronto's streetcar and subway lines, it has standard gauge tracks.
Current proposals are for the Scarborough RT to be rebuilt as a light-rail line, beginning in 2015, to use a new fleet of light rail cars, replacing the line's current fleet. Scarborough RT riders will be bussed for three years until the rebuilding is completed.[5]

In 1972, the provincial government announced the GO-Urban plan to build an intermediate capacity transit system across suburban Toronto using the experimental Krauss-Maffei Transurban.[6] The system failed to function to come to fruition, and the TTC began building the line for CLRV streetcars, but the ICTS system was used instead, because the Province of Ontario agreed to pay a large portion of the costs. This change was made after construction had commenced. At Kennedy Station, there are clues revealing that it was originally built for streetcar operation; it is possible to see old low-level streetcar platforms protruding under the current high-level platforms, and Kennedy Station originally had a loop to turn streetcars. This proved too sharp for safe operation of SRT cars, which didn't have a reason to turn around, and the loop was replaced by a Spanish solution-like crossover.[7] Ontario wanted to develop and promote its new technology, which was originally designed for a proposed urban GO Transit service known as GO-ALRT. Changes to federal railway regulations had made the new system unnecessary for GO, and so the government hoped to sell it to other transit services in order to recoup its investment.
The Scarborough RT opened in March 1985. Three years after it opened, the TTC renovated its southwestern terminus at Kennedy Station, because the looped turnaround track, originally designed for uni-directional streetcars under the earlier plan and not needed for the bi-directional ICTS trains, was causing derailments; it was replaced with a single terminal track and the station was thus quasi-Spanish solution, with one side for boarding and another side for alighting, though the boarding side is also used for alighting during off-peak hours.
The line has seen no extensions since it opened. Many transit advocates believe that it would have been wiser either to build it using streetcars, as was originally planned, to allow for lower costs and more flexibility in route options or simply to extend the underground Bloor–Danforth line further into Scarborough (for more details, including the proposal to combine it with the Eglinton Crosstown line, see Future below).
Service
Trains
The trains operated were developed by the Urban Transportation Development Corporation (UTDC), then an Ontario Crown corporation but now a division of Bombardier Transportation. The business proposal initially bore little fruit – a proposed pilot project in Hamilton was cancelled after meeting widespread public opposition, and the technology was used initially only by the Scarborough RT, Vancouver's SkyTrain, and the Detroit People Mover. With expansion of the SkyTrain and sales to Ankara, Turkey; Kuala Lumpur, Malaysia; New York City's John F. Kennedy International Airport AirTrain, and Yongin EverLine in Yongin near Seoul, South Korea,[8] redesigned, sold under the name "ART" (advanced rapid transit), has become a success for Bombardier.
One unusual feature of the ICTS cars is that they are driven by linear induction motors: instead of using conventional motors to turn the wheels, they push themselves along the route using alternating flat magnets reacting with the distinctive di-magnetic aluminum metal plate that runs down the centre of the tracks. This system requires very few moving parts, and therefore leads to lower maintenance costs.
When the car motors are accelerating, they actually lift the car off the track an extremely small distance, repelling against the wide aluminum plate in the centre of the track.[9] This micro-lifting prevents the truck wheels from making a solid electrical contact with the track. Instead of using the conventional method, in which motive power is supplied by a single third rail, with return current travelling through the running rails, a separate positive and negative power rail are provided on one side of the track. With respect to the accelerating trucks and the micro-lifting, the truck wheels have a somewhat larger flange than normal in order to keep the car inline on the track during the micro-lifting.
The linear induction motors also allow the cars to climb steeper grades then would be possible with traditional subway technology since wheel slip is not an issue. This is an important consideration when trying to build a rail transit system into a built-up urban environment, such as Toronto.
The trains are also able to be operated exclusively by computers, using Standard Elektrik Lorenz's "SelTrac IS" system (now[when?] owned and delivered by Thales Canada Transportation Solutions), doing away with the need for a human operator. However, due to union opposition and public perception, operators were retained. (Other systems took full advantage of the automated operation and Vancouver's Sky Train has been automated since 1985 with no mishaps.) The Scarborough RT trains have only one operator, unlike TTC subway trains, which carry both a guard, who operates the train's doors, and an operator, who drives. In practice, the Scarborough RT trains drive themselves; the operator monitors their operations and controls the doors. The transit workers' union has firmly opposed driverless trains.[10] One feature, which was not implemented at the Scarborough RT's opening, is the automated stop announcement system, which was introduced in January 2008.
Route
The line follows a roughly L-shaped route: first northward from Kennedy Station, parallelling the Canadian National Railway/GO Transit's Stouffville line tracks, between Kennedy Road and Midland Avenue, 4 km (2.5 mi) to Ellesmere Road; then eastward between Ellesmere and Progress Avenue, through Scarborough City Centre to McCowan Road. The Scarborough RT's ICTS trains have their own small yard east of McCowan Station. This yard is large enough to store the existing fleet, but would have to be expanded or replaced if the TTC were to expand the line's capacity with new trains. Basic maintenance is performed in this yard; for more extensive work the cars are taken to the subway's Greenwood Yard by truck, given the train's different track gauge. The north-south section of the route, where it follows the CN tracks, is at ground level; the shorter east-west section (except for the ground-level yard) is elevated, as is the Kennedy terminus. The line dives briefly underground just north of Ellesmere Station to cross under the CN tracks. After that, it is elevated towards McCowan station.
All stations, whether by transfer or fare-paid terminal, connect to surface TTC bus routes. Other connections are noted below.
Two stations, Kennedy and Scarborough Centre, are wheelchair accessible.
There have been proposals to add a station at Brimley Road, due to the increased number of residential developments in the area of Brimley and Ellesmere Roads.[citation needed]
Very early in the morning when the Scarborough RT is not operating, the 302 Danforth Rd-McCowan Blue Night bus serves the same area. The 302 originates at Danforth and Warden, where it connects with the 300 Bloor–Danforth that travels to the west. From Warden, the 302 travels east along Danforth to McCowan, then north along McCowan to Steeles. With the exception of McCowan RT station, it does not pass near any of the subway or RT stations, though other night bus services pass near stations. Bus service is extended on Sundays because the subway and RT start at 9 a.m. instead the usual 6 a.m. start.
Future expansion
Controversy
The Scarborough RT has long been maligned for many reasons. Because it uses advanced propulsion technology and standard track gauge (unlike the rest of Toronto's system), it can not interchange with Toronto's subway or streetcar lines. Since the line was built to handle smaller vehicles, Toronto's subway trains would not be able to handle its tight curves.[11] The TTC's fleet of Mark I vehicles is aging and demand has exceeded the capacity of the TTC's Mark I fleet,[12] but these vehicles are no longer produced by Bombardier, leaving the TTC with the prospect of either retrofitting the line for Mark II vehicles (used successfully along with Mark I vehicles in Vancouver) or streetcars; or paying Bombardier to restart the production of Mark I vehicles. Most critics[who?] of the line point to the fact that the demand is not such that it requires "Rapid Transit". The TTC itself estimates potential demand at no more than 10,000 passengers/hour/direction,[13] which could be served by streetcars running in a grade-separated right of way in 2015.[14]
Proposals
In 2006, a study was completed on the prospects of this line.[15] It recommended upgrading the line to handle larger ART Mark II vehicles, at a cost of $360 million (2006 dollars). Extending the Bloor–Danforth line (either along the current Scarborough RT route, or along a different alignment directly to Scarborough Centre) was not considered cost-effective or justifiable.
On June 15, 2007, the Ontario government had released MoveOntario 2020, a plan that would fund 52 different transit projects throughout Toronto and Hamilton for the cost of $17.5 billion, including the Scarborough RT extension to Sheppard Avenue, which would meet the proposed Sheppard East LRT line, also to be funded by MoveOntario 2020.[citation needed]
Since 2008, the TTC is assessing an extension of the SRT from McCowan to Malvern Town Centre.[16] They have also made a motion that the current study should include the addition of a station where the existing line crosses Brimley Road.[17]
On April 1, 2009, the Ontario government will help fund a plan to expand the Scarborough RT east towards either Markham Road, or further northeast to the Malvern Town Centre and to replace its existing vehicles along that line.[18] The expansion and its upgrades should be completed by 2015.[19]

In September 2009, Scarborough Community Council recommended, with Toronto City Council officially passing on to the TTC and Metrolinx, a proposal to replace the RT's ICTS technology with the LRT technology of Transit City. This would have all surface and elevated RT systems in Scarborough use interchangeable technology, and ironically return the RT to its originally-planned system.[20] Efforts had been underway to have the replacement completed by the summer of 2015, in time for the Pan Am games;[21] however, due to provincial budget issues, this had to be delayed. The line will remain as ICTS into 2015, supplemented with second-hand cars from Vancouver; once the Games are completed, the conversion to Transit City technology will be undertaken.[22] However, Rob Ford, who became mayor on December 1, 2010, had plans to replace the Scarborough RT with an extension of the Bloor-Danforth line.[23]
In March 2011, Ontario Premier Dalton McGuinty announced the allocation of $12.4 billion of future expansion of the Toronto subway and RT, part of which will cover the expense of rebuilding the Scarborough RT to use modern light rail cars. The line would also be extended westward from Kennedy station along Eglinton Avenue until west of Black Creek Drive in York collectively to form a new Eglinton–Scarborough Crosstown line.[24] As part of the rebuilding, it was expected that Ellesmere station will be closed due to low demand.[25] As of 2012, the plan to connect the line with a line along Eglinton Avenue was dropped after Toronto City Council decided that light rail transit on Eglinton Avenue must not be constructed entirely underground as a premetro. The Scarborough RT will still be upgraded to run the same fleet of vehicles that were previously proposed to replace the current fleet, but the line will continue to function independently with no mergers expected to be done. The line is also expected to be extended north-east from McCowan to the neighbourhood of Malvern.
