The TTC's current fleet of 248 streetcars is nearing the end of its useful life, and the TTC will be buying at least 204 new LRVs. The commission has stated that potential bidders for the new contract must propose a 100% low-floor vehicle. These new vehicles will likely be costly, as the TTC's network has unique challenges, such as steep grades on hills (up to 8%), many extremely sharp curves (as little as 10.973 m or 36 ft in radius), and a unique track gauge of 1,495 mm (4 ft 10
7⁄8 in). The commission intends to customize a model that meets approximately 75% of its criteria. Bombardier Transportation won the bid with its Flexity Outlook model. The new streetcars, customized Bombardier Flexity Outlooks, are set to be built and in service as soon as 2014.
The TTC has retained two PCC streetcars (#4500 and #4549) and one Peter Witt streetcar (#2766) primarily for charter service.
However, during the summer of 2009 and 2010, the TTC ran one of its two PCC cars on the 509 Harbourfront route on Sundays between May and the Labour Day weekend. In previous years, one of the PCC cars would run along the Harbourfront route on holidays during the summer.
The TTC has begun on-street testing of its new streetcar fleet, having successfully run the first test vehicle from the TTC’s Bathurst St. facility (Hillcrest) to Bathurst Station and back in the early hours of March 14, 2013.
Plans call for the new streetcar to serve the 510 Spadina line first. As production vehicles arrive and are commissioned by the TTC, more streetcar routes will begin to be serviced by the new car. Full deployment across the streetcar network is expected by 2018.
Taken sometime last week in Toronto.
