Item - 2025.TTC6.3

The TTC Board:

1. Received the PEDs Study report.

2. Approved addition of PEDs requirements, including operational and technical system requirements to the TTC Design Manual and Master Specifications for implementation at future new stations.

3. Referred the implementation of a platform-edge door pilot installation at a TTC station, including funding based on estimates, to the Strategic Planning Committee for consideration to be included as part of the 2026 budget submission.

4. Approved ongoing planning work, including prioritizing stations for implementation of appropriate technologies based on specific needs and drivers of each station.

5. Requested that staff provide the Strategic Planning Committee with class 5 estimates of the costs and benefits to the TTC of technically feasible options to detect or discourage track-level intrusions at subway and LRT stations, including those being installed by Metrolinx on new stations in Toronto.

The purpose of this report is to outline the outcome of a system-wide study on Platform Edge Doors (PEDs) and other technologies being considered for implementation at existing TTC subway stations. PEDs are identified in the TTC's Corporate Plan in Action 3.1.4, Evaluate Opportunity to Integrate Platform Edge Doors into Subway Improvements.

A new approach is necessary to manage the interface between TTC customers, communities, and subway train operations, which reduces service disruption caused by track intrusions. PEDs have been identified as a potential mitigation strategy to prevent unauthorized track entry and injury incidents that affect subway operations and enhance customer safety.

The study aimed to assess the benefits of retrofitting 74 existing subway station platform levels, including interchange station platforms across Subway Lines 1, 2 and 4, with a Full-Height PED system. The PEDs study was comprised of three phases:

• Preliminary Investigation: It reviewed the conditions of existing subway stations.
• Feasibility Study: It assessed retrofitting the existing subway station platform with PEDs.
• Business Case: It quantified benefits, costs, and socioeconomic impacts.

A one-size-fits-all approach will not be considered. The type of PEDs for each station will be determined based on station-specific needs and drivers, including community dynamics. In addition to Full-Height PEDs, various technologies were reviewed as part of this study, including Sensor-Based Track Intrusion System, Guideway Intrusion Detection System, Partial-Height PEDs, and Rope-Based Platform Screen Doors.

The implementation of PEDs at existing stations will require extensive planning, with the majority of the work taking place at track level during non-operating hours, and will need to be implemented alongside ongoing State of Good Repair (SOGR) work in subway tunnels and stations. Implementation of the PED system as part of major works, such as Bloor-Yonge Capacity Improvements (BYCI) will minimize operational and customer disruptions while addressing cost and schedule efficiency.

Extensive subway station closures and station bypasses will be necessary to effectively complete track-related work for the PED system and to minimize the challenges. Partial and full closures of subway lines and stations were used in Paris, Hong Kong, Singapore, Copenhagen, and Seoul’s Metros to successfully retrofit the PED system in existing stations.

The PEDs study recommends a pilot installation be undertaken at one or more stations with various structure types to identify and mitigate implementation challenges. This would require the TTC to seek funding and approval to implement a pilot installation. A pilot implementation at TMU Station (currently Dundas) is recommended to evaluate impact, refine design, and address challenges before a broader rollout. Additional PEDs integration at Bloor-Yonge Station is also being reviewed, but currently unfunded.
