207-516: A cost of $ 357.4 million. In April 2022, the TTC recommended that the Line 3 right-of-way between Kennedy and Ellesmere stations be converted into a 4-kilometre (2.5 mi) dedicated busway after the Line 3 closure. There would be stops along the right-of-way at Mooregate Avenue / Tara Avenue (approximately halfway between Eglinton Avenue and Lawrence Avenue), Lawrence Avenue East and Ellesmere Road. Between

Metrolinx had declined a TTC request to give an opinion prior to City Council's July 2016 vote. In 2017, the estimated cost of the one-stop Line 2 extension was $ 3.35 billion, which increased to $ 3.9 billion by April 2019. On April 10, 2019, Premier Doug Ford announced that

414-538: A problem. On July 13, Toronto City Council voted down Matlow's proposal by a margin of roughly 2 to 1. Councillor Glenn De Baeremaeker justified the subway extension saying "Scarborough residents need the same access to a subway system that everybody else already has." Mayor Tory was concerned that switching from subway to LRT would delay transit improvements in Scarborough, and might not get support from senior levels of government. In September 2013, Metrolinx prepared
483-541: A proposed Crosstown East LRT line extension of Line 5 Eglinton. The eliminated intermediate stops were at Lawrence Avenue and Sheppard Avenue. Subsequently, the cost estimate for the one-stop subway extension increased to $ 3.2 billion, leaving the Crosstown East LRT unfunded. Given the rising cost for the subway extension and the loss of funding for the LRT line, a group of city councillors led by Josh Matlow reopened
552-447: A reason to turn around, so the loop was replaced by a single-track Spanish solution -like crossover. Ontario wanted to develop and promote its new technology, which had been designed for a proposed GO Transit urban service known as GO-ALRT . Changes to federal railway regulations had made the new system unnecessary for GO, so the government hoped to sell it to other transit services in order to recoup its investment. The Scarborough line
621-458: A single line called the "Eglinton–Scarborough Crosstown line", Metrolinx proceeded with plans to convert the line to light rail and extend it to Sheppard Avenue with a single new intermediate station at Centennial College. The existing line would have closed after the 2015 Pan American Games and be completed in 2020. In January 2013, Infrastructure Ontario issued a request for qualifications to shortlist companies to construct both this line and
690-409: 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, weekends and holidays. With the line approaching the end of its useful life, the TTC reduced the frequency of service in mid-September 2012 to reduce wear and tear on both the aging rolling stock and

As of April 2019 , there are plans to replace Line 3 with the three-stop Scarborough Subway Extension of Line 2 from Kennedy station to Sheppard Avenue , with intermediate stops at Lawrence Avenue and Scarborough Town Centre . With an estimated completion between 2029 and 2030, the extension would follow a different route than Line 3. The Government of Ontario has committed to fully fund its $ 5.5-billion cost. In February 2021,

#1733084767609828-517: A train derailment in July 2023 resulted in the line permanently closing four months ahead of schedule. By March 2023, a plan existed to convert a portion of the existing right-of-way between Kennedy and Ellesmere stations into a bus right-of-way, including an additional stop at Mooregate Avenue / Tara Avenue, located near a pedestrian bridge that spans over the former Line 3 and GO Transit's Stouffville line between Eglinton Avenue and Lawrence Avenue.

The line ran entirely within
966-634: The S-series cars. If the problem were not rectified, there would be the risk of serious structural damage to the cars. That would have prevented the cars from lasting until 2026 when the Scarborough Subway Extension was scheduled to replace Line 3. The repair work required service to be reduced from 6 four-car trains down to 5. On July 24, 2023, the last car of a train on Line 3 Scarborough derailed south of Ellesmere station. There were 45 people on board, with five injuries reported. The TTC closed
1035-487: The Detroit People Mover was projected to take over a year and a half. The purchase would replace the system's existing train sets with upgraded features, along with providing much-needed parts needed to keep the system functional. Line 3 used 5-rail track, which a TTC document describes as follows: Track is the 5 rail system on direct fixation and car is powered by an induction or " reaction rail " situated between

In June 2013, Toronto City Council again debated having the Scarborough line replaced with an extension of Line 2 Bloor–Danforth north to Sheppard Avenue along a different right of way. Metrolinx issued a letter to Toronto City Council indicating it would cease work on
1173-677: The ICTS design for the line would not allow for the interchange of rail equipment between lines 2 and 3 even if they were both the same gauge. The line followed a roughly inverted L-shaped route when viewed northwards: first from Kennedy station, paralleling the Canadian National Railway / GO Transit's Stouffville line tracks, between Kennedy Road and Midland Avenue, 4 kilometres (2.5 mi) to Ellesmere Road; then eastward between Ellesmere Road and Progress Avenue, through Scarborough City Centre to McCowan Road . The north–south section of
1242-408: The LRT was estimated to cost $ 1.48 billion to build versus $ 3.56 billion for the Line 2 extension; both estimates would subsequently increase. Converting Line 3 to light rail would require the complete shutdown of the line while extending Line 2 could occur without requiring a Line 3 shutdown. Circa 2013, this was promoted as a major benefit of the Line 2 extension over a conversion to light rail. At
1311-402: The Line 3 shrink wrap is removed but not re-applied yet. These were followed by interior upgrades, such as using coloured velour seating. On December 13, 2016, Presto fare gates were installed at Lawrence East station , making all stations along this line Presto-enabled. On April 18, 2017, the TTC awarded a $ 6.8-million contract to Bombardier to repair corrosion damage under the floors of
1380-453: The Murray plan, there would be only two stations and there would be no direct connection with the then-proposed Sheppard East LRT. The Murray plan would have required the relocation of Kennedy station as a new northbound curve from the existing Kennedy station would have been too tight for subway trains. It would also have required the complete shutdown of the line during construction, something that
1449-451: The Scarborough line trains drove themselves ; the operator monitored their operations and controlled the doors. One of the features which was not implemented at the time of Scarborough line's opening was the automated audible-only next-stop announcement system, which was introduced in January 2008 and meant operators were no longer required to announce stops manually. These announcements feature

#17330847676091518-647: The Scarborough portion of the line, because its position strayed from the original LRT agreement. The subway alternative would cost between $ 500 million and $ 1 billion more than converting the Scarborough line to use the same rolling stock as the Eglinton Crosstown line be so it could be a continuation of that line. The Globe and Mail reported that Scarborough councillors had argued that providing Scarborough residents with light rail, not heavy rail, treated them as "second-class citizens". Two competing subway plans were proposed to replace Line 3. TTC chair Karen Stintz proposed extending Line 2 Bloor–Danforth to
1587-640: The Stintz plan avoided. On October 8, 2013, Toronto City Council voted 24–20 to replace the Scarborough line with a three-station extension of the Bloor–Danforth subway line. Council chose the Stintz plan for the extension. In 2013, the rejected LRT proposal would have provided a 9.9-kilometre (6.2 mi) line with seven stops serving 47,000 residents within walking distance. The selected 3-stop subway extension would be 7.6 kilometres (4.7 mi) long, serving 14,000–20,000 residents within walking distance. In 2013,
1656-465: The TTC recommended closing Line 3 permanently by 2023 and replacing it with bus service until the Line 2 extension opens. Once Line 3 is closed, portions of its right-of-way could be converted into parkland . In 2006, a study was completed on the prospects of the Scarborough line. It recommended upgrading the line to handle larger Innovia Metro Mark II vehicles, at a cost of $ 190 million (in 2006 dollars) with an eight-month service suspension for
1725-441: The TTC recommended shutting down Line 3 permanently in 2023 and replacing it with bus service. The TTC rejected doing a third overhaul of the line because it would cost $ 522.4 million and might not improve its reliability. The TTC offered two bus replacement options: purchase 60 hybrid buses by 2023 for $ 374.8 million or reduce the number of spares for maintenance, deferring the purchase of new buses until 2027 to 2030, at

The 302 originates at Bingham Loop , where it connects with the 322 Coxwell bus that travelled to the west, as well as Route 324 Victoria Park that runs north. From the loop, Route 302 travels east along Kingston Road to Brimley Road, then north along Brimley Road to Danforth Road, then north on McCowan Road to Steeles Avenue. With
1932-462: The busway was targeted for completion by 2025. From when the line opened in 1985 until 2015, it was known as the "Scarborough RT" or "SRT". The "RT" in Scarborough RT stood for "rapid transit". The name Scarborough Line was used on the official TTC website and 2014 TTC Ride Guide. In October 2013, the TTC announced plans to give the lines official numbers to help riders and visitors to navigate
2001-528: The cost estimates for "delays" was unnecessary, which assumed the LRT's completion would be in 2026, the same date as the subway option. However, according to Michael Warren, a former TTC chief general manager, the LRT could have been completed in 2020 at a cost of $ 1.8 billion, an estimate not presented to City Council when it voted. There was also the issue of whether there would be space for both expanded GO service and an LRT north of Kennedy station; however, Metrolinx subsequently denied there would be such
2070-530: The cost savings would be great enough to overcome difficulties such as the incompatibility of Mark II cars with the existing line geometry and the extra cost of building a fully separated right-of-way to Sheppard Avenue, where Line 3 could connect with either a proposed extension of Line 4 Sheppard or the Sheppard East LRT . The TTC and the City of Toronto completed an environmental assessment in 2010 to convert

2415-493: The exception of McCowan station , it does not pass near any of the rapid transit stations, though other night bus services pass near stations. Bus service was extended on Sundays because the rapid transit lines started at 8 a.m. (beginning January 3, 2016) instead of the usual 6 a.m. start. Service frequency was 30 minutes. The frequency for this line was 4 to 5 minutes during peak periods and 5 to 6 minutes during off-peak periods. The TTC operated five to six trains on

In late September 2023, the TTC explained that bolts that held the linear induction rail to the roadbed had come loose in the July incident, causing
2967-438: The line with each train consisting of four cars. There are 28 cars in the Line 3 fleet. Line 3 trains could switch directions only at the ends of the line as there were no intermediate crossovers between the two termini. Thus, there could be no short turns on Line 3. In winter, during heavy snow or freezing rain, the TTC previously ran "storm trains" overnight on Line 3 to keep power rails clear of ice, and apply anti-freeze to

Immediately following the derailment, replacement bus service was implemented initially by shuttle buses serving the closed stations along Line 3. On September 3, 2023, the TTC replaced the shuttle bus service with route 903 Kennedy–Scarborough Centre Express, running northbound on Kennedy Road and southbound on Midland Avenue in reserved lanes between Kennedy and Scarborough Centre stations. Unlike
3105-399: The need for a human operator. However, due to opposition from the transit workers' union and public perception, operators were retained; the union has firmly opposed driverless trains. (Other systems took full advantage of the automated operation and Vancouver's SkyTrain has been automated since 1985 without incident.) The Line 3 trains had only one operator since inception. In practice,
3174-476: The plans. Extending Line 2 Bloor–Danforth, either along the current route or along a different alignment directly to Scarborough Centre station, was not considered cost-effective or justifiable. In November 2015, transportation consultant and University of Toronto professor emeritus Richard Soberman argued that it would be vastly cheaper and faster to buy new Line 3 vehicles than to replace Line 3 with an extension of Line 2 northeast from Kennedy station. He felt

Thus, about two hours before an expected storm, the TTC may have decided to shut down Line 3 and replace it with bus service. Just before the storm of February 2, 2022 , the TTC replaced all Line 3 trains with 25 buses. The Scarborough line's S-series ICTS trains were stored and serviced at

Line 2 would also receive new subway trains as part of the extension to replace the existing T1-series trains. On April 10, 2019, Ontario premier Doug Ford announced that Line 3 Scarborough would be replaced by a three-stop extension of Line 2 Bloor–Danforth to be completed by 2030. However, on December 10, 2020, Toronto mayor John Tory stated that Line 3

TTC CEO Andy Byford said the cost of the LRT line following the Line 3 route may have risen to as high as $ 3 billion because of "delays and redesign" since 2013, but Brad Ross, also of the TTC, warned of "caveats around numbers and assumptions" associated with that estimate. After Council's vote, Byford admitted that
