en.Wedoany.com Reported - The Toronto Transit Commission (TTC) has signed a contract valued at approximately $407.7 million (about C$550 million) with Hitachi Rail Canada to replace the signaling system on the Bloor-Danforth Line 2 of the subway. The line spans 16.3 miles with 31 stations and will be equipped with Communications-Based Train Control (CBTC) technology. Preliminary design and engineering work begins this year, with the project expected to be fully completed by 2037.
Under the contract, Hitachi Rail will design, test, and deliver the SelTrac CBTC system at its Canadian headquarters in Toronto. The new system handles automatic speed control and train spacing management, enabling more precise train position monitoring and replacing existing fixed-block signaling with moving-block signaling, allowing trains to operate at shorter headways while maintaining safe separation. The project adopts a phased implementation approach, with the design and engineering phase extending through 2028, followed by phased deployment across the line.
The project is scheduled to begin in 2026 and be completed in 2037. Once the system is fully operational, peak-hour capacity on Line 2 is expected to increase from 23,400 to up to 33,000 passengers, representing a maximum increase of approximately 40%. As of this publication, the TTC has not disclosed the number of train sets requiring onboard CBTC equipment, nor the specific implementation milestones for each phase between 2028 and 2037.
For reference, the New York Metropolitan Transportation Authority (MTA) finalized a $1.5 billion contract in 2024 to procure new subway cars with CBTC compatibility and allocated signal modernization funding for 8 lines covering more than 75 miles of track in its 2025–2029 capital plan; the MTA has tied CBTC deployment to congestion pricing revenue, a financing mechanism that differs from the TTC's capital procurement approach. On a per-line-mile basis, the Line 2 contract equates to approximately $25 million per mile, which falls within the typical range for CBTC overlay projects on existing lines, though total per-mile costs can vary significantly depending on fleet size, station configuration, and interoperability requirements with existing systems.

The TTC's Line 1 CBTC system has been in operation since 2022, with a corridor length similar to Line 2, providing an internal institutional benchmark for this deployment. Hitachi's SelTrac platform is currently operating across multiple systems, including TTC Line 1, Vancouver's SkyTrain, and London's Docklands Light Railway.
Line 2's approximately 11-year delivery timeline reflects the practical constraints of retrofitting signaling systems under continuous operating conditions, a challenge commonly faced by CBTC upgrades on existing metro lines worldwide. This contract also aligns with the expansion trajectory of the digital railway market: market research firms Market.us and RailMarket project the market to reach $296.7 billion by 2035, with signal modernization representing a major expenditure category for existing metro operators in North America and Europe.

CBTC determines a train's precise position and speed through continuous radio communication between the train and wayside equipment, enabling trains to automatically maintain safe distances at shorter intervals. Line 2 passengers will fully benefit after the project's completion in 2037, with incremental capacity improvements experienced during the phased implementation after 2028; Line 1 underwent a similar process before full CBTC deployment in 2022. Regarding per-mile costs for the two lines, the TTC has not publicly released direct comparative data; published information shows the Line 2 contract at approximately $407.7 million, covering 16.3 miles of track and 31 stations, with deployment experience from Line 1 expected to reduce technical risk for the new project.
