On December 9, 2024, the TTC issued Requests for Proposals for two major contracts affecting the future of Line 2 Bloor-Danforth: one for new trains, and the other for a new signalling system.
Although the documents for these RFPs total over 2,700 pages with detailed specifications for cars and signals, round one of the process is intended to establish the basic capabilities of would-be suppliers to actually handle the contract without getting into the nitty-gritty. Following rounds will get into the technical details and negotiations.
The RFP process for round one closes on January 28, 2025 (trains) and on January 27 (signals). Contract awards will occur in 2026.
Major points:
- The two projects/contracts are linked because implementation of Automatic Train Control on Line 2 requires a new fleet. ATC installation can run concurrently with new train deliveries, but the benefits of ATC operation are not possible until the existing Line 2 fleet of T-1 trains is replaced.
- As a separate project, the T-1s will be overhauled to keep them running into the 2030s, although they will be retired as new trains are delivered.
- The new trains RFP includes provision for additional equipment including trains needed for extensions of Lines 1 and 2, and for improved service on Line 1. The timing of train deliveries for Line 2 could bump into requirements for Line 1 trains thereby delaying the Line 2 cutover to ATC. Additional trains for Line 1 also trigger the need for a new carhouse which is not yet a funded project.
- Growth in capacity of Lines 1 and 2 beyond 2019 levels could be constrained by the availability of fleet and infrastructure. This has already shown up in the planned completion of the ATC cutover on Line 2 in 2035. This date conflicts with TTC projections of demand growth.
- Although the RFP for new trains is theoretically open to all bidders, both the provincial and federal governments have made statements about how this will guarantee work for Thunder Bay. Bidders might well ask if any firm but Alstom actually should bother participating. Options within the RFP include future replacement of the Line 1 TR fleet which, based on a 30-year lifespan, would stretch from 2039 to 2047.
- The Line 2 ATC RFP is also an open bid, and it explicitly states that if a different vendor from Line 1 (Alstom) is chosen there will be Line 1 and 2 trains with different vendors’ ATC gear. The trains will not be able to interoperate between the lines except in manual (“emergency”) mode at restricted speed.
- Work cars need dual capability and the TTC intends to equip them with gear that can work with either the Line 1 or 2 system. What this might entail both for physical space on the cars, operating procedures and complexity is not discussed.
- If train frequencies are improved beyond 2019 levels (less than 140 seconds), there will be capacity issues at terminals and turnbacks. The ATC RFP includes a performance requirement for faster turnarounds (as low as a 100 second headway) but it is not clear whether this is possible with existing track geometry.
- The Scarborough Subway will be built with conventional block signals, and will be retrofitted with ATC in a later, as yet unfunded, project. It is not yet clear whether full service will operate during peak periods on the SSE during peak periods, and the ATC RFP provides for turnback operations in a tail track east of Kennedy Station.
- Funding for future stages beyond 70 cars (55 for Line 2, plus 15 for the Scarborough and Yonge North extensions) is not guaranteed.
