The problems of continuing to use Davisville Yard are:
It is recommended that the Commission approve the following recommendations noting that the attached report Yonge-University Spadina Line – Subway Rail Yard Needs Strategy was deferred at its meeting of November 17, 2009:
- Approve the Subway Rail Yard Needs Strategy (SRYNS) to provide sufficient yard capacity to 2030 (based on Option 2A) for the Yonge-University-Spadina (YUS) line noting that functional planning/scope definition to implement the strategy is currently underway and will be reflected in the future TTC Capital Program;
- Forward this report to York Region and the Town of Richmond Hill for their information concerning the implementation of the Richmond Hill extended tail track (14 trains) and post 2030 Yonge Subway Yard requirements, noting that the Richmond Hill extended tail track is a key component of implementing recommended Option 2A;
- Forward this report to Metrolinx and the City of Toronto for their information, noting that the full implementation of the SRYNS will impact the TTC Capital Budget and the budget for the Yonge Subway Northern Extension Project;
- Authorize staff to take the necessary steps to identify a suitable property that could be purchased within the next 10 years to protect for the design and construction of a future storage and maintenance yard on the Yonge Subway side of the YUS line in order to protect the long term/strategic rail yard needs of the TTC beyond 2030 and approve, in principle, the inclusion of funds in the outlying years of the 2011-2020 Capital Program for the purchase of a new yard on the Yonge Subway side of the YUS line to provide staff with the flexibility to purchase a suitable property should one become available for sale; and
- Endorse staff’s inclusion of a subway rail yard needs analysis for the Bloor-Danforth Subway line to identify long term yard requirements to 2030 and beyond as part of the 2011-2015 Capital Program.
The 5 options mentioned are:
1—Limited Wilson Yard Expansion
2—Full Wilson Yard Expansion
2A—Full Wilson Yard Expansion/Continued use of Davisville Yard for Limited Revenue Service Trains
3—New Yonge Storage and Maintenance Yard
4—New Yonge Storage Yard
5—Same as Option 2 plus Sheppard Subway (Yonge – Downsview)
2—Full Wilson Yard Expansion
2A—Full Wilson Yard Expansion/Continued use of Davisville Yard for Limited Revenue Service Trains
3—New Yonge Storage and Maintenance Yard
4—New Yonge Storage Yard
5—Same as Option 2 plus Sheppard Subway (Yonge – Downsview)
The problems of continuing to use Davisville Yard are:
For Davisville Yard, the following operational considerations are currently apparent:
− The existing yard/carhouse is designed for 2 car married pairs not 6 car Toronto Rocket train consists;
− It relies on turn back operations to operate the yard;
− With the Toronto Rocket fleet at Davisville Yard, the number of cars that can be stored/cleaned overnight will be reduced compared to the present capacity due to the 2 car consist track layout;
− The yard is well situated to supply trains to the YUS line but is surrounded by high density residential uses that are sensitive to yard operations;
− It is not considered practical or cost effective to expand Davisville Yard given property constraints. Davisville Yard is constrained by existing apartment buildings to the south and west, the park to the north west, and the existing carhouse/YUS mainline to the north and east. It is not considered practical to extend the existing track arrangement to accommodate 6 car TR train consists or to expand the capacity of the yard in a significant way by acquiring additional property. The displacement of existing yard functions to the west of the existing Carhouse to accommodate additional storage capacity for 6 car trains is also not operationally desirable and is not recommended. As a result, expansion of Davisville Yard was not considered a viable yard expansion strategy.
− With the Toronto Rocket fleet (6 car train consists) and assuming no expansion of Davisville Yard, there will be storage tracks (which are designed for 2 car married pairs) that may be available for other yard functions. The consolidation of the majority of the maintenance/storage of the non-revenue vehicle fleet at Davisville Yard to take advantage of the unused portion of the yard (post Toronto Rocket fleet implementation) was therefore considered a base case for all future strategic yard operations analyzed in the SRYNS.
