Item - 2025.TTC6.3

It is recommended that the TTC Board:

1. Receive the PEDs Study report.

2. Approve 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. Direct staff to include funding based on estimates for the implementation of a pilot installation at TMU Station (Dundas) as part of the 2026 budget submission.

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

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.

Funds for the PEDs Study is included in the TTC's 2025-2034 Capital Budget and Plan under Capital Program 3.9 – Platform Edge Door Study, as approved by the TTC Board at its meeting on January 10, 2025 and by City Council at its meeting on February 11, 2025. The total project budget is $1.55 million comprising of $1.45 million to the end of 2024 and $99,000 in 2025.

The total capital cost for the implementation of the PEDs system for Lines 1, 2 and 4 is estimated at $4.1 billion, with average costs of $44 million to $55 million for two platforms of a station based on the preliminary (Class 5) cost estimate, which includes a cost escalation to the midpoint of construction projected in 2036. The estimated cost was also included in the 2025-2039 Capital Investment Plan and remains unfunded.

Subject to the approval of the recommendations of this report and available funding room available, $44 million will be included in the 2026-2035 Capital Budget and Plan submission for the implementation of a pilot installation at TMU Station (Dundas) for Board consideration. The preliminary cost estimate does not include the ATC interface. This will be further reviewed and discussed with the Line 1 ATC supplier as the PEDs project progresses and an implementation strategy is developed.
