TTC prepares to install automatic train signalling, promises more frequent service

Toronto's transit agency is set to modernize its subway system by upgrading the signaling technology on Line 2, the Bloor-Danforth line. The Toronto Transit Commission (TTC) has signed an agreement with Hitachi Rail Canada to install a communications-based train control (CBTC) system.

This advanced system automatically manages train speed and distance, enabling them to operate closer together. The TTC anticipates this will significantly increase service frequency and reduce delays for passengers. "We're modernizing the TTC by investing in systems that increase capacity, improve reliability, enhance safety and support a growing city," stated TTC CEO Mandeep Lali in a news release. He added that CBTC represents "the next evolution in signalling, enabling us to better manage trains in real time and deliver more frequent service to customers."

The new CBTC system has been in operation on the Yonge-University line for the past three years. However, the implementation on the Bloor-Danforth line is a more extensive project. The TTC has announced that the work will commence in 2028 and is projected to be fully operational by 2037, a timeline of about a decade.

This upgrade is part of a broader effort to enhance the TTC's infrastructure and capacity to serve a growing city. The investment in modern signaling technology aims to improve overall service reliability and safety, ensuring a more efficient transit experience for Torontonians.
