Thanks for your feedback and questions on the Scarborough Junction Grade Separation Project.

The horizontal and vertical geometry of the infrastructure has been designed to meet GO operational requirements. Final track arrangement, including locations and type of special track works (turnouts and crossovers) will be determined during the detailed design phase of the project together with the successful proponent who will design, build, operate and maintain the new the new infrastructure.

Regarding the possible use of pantograph on the electrification system, please refer to Metrolinx Engage site: https://www.metrolinxengage.com/en/content/what-involved-electrification.

The successful proponent team will be responsible for selecting and delivering the right trains and infrastructure to unlock the benefits of GO Expansion. The contract is in a multi-year procurement process, and currently teams are completing the bids that will close in 2021. Construction will get underway in 2022.

1) Remember that the present Bi-level vehicles are designed to negotiate a horizontal curve of 250 ft. Check the corresponding vertical curve.
2) Will high-speed switches be used for both the north and south rail lines?
3) The Bi-level vehicles are designed to an AAR Plate "H" clearance diagram. If the route is to be electrified adjust vertical clearances accordingly.
4) Recall that the iconic shape of the Bi-level car was developed so that at some point in their design life they could accept a pantograph (sliding conductor). Never has such a vehicle been so mocked-up.

Thank you for your comment. The preliminary design does not necessarily reflect finishes and landscaping that may be applied to the infrastructure. Existing landscaping and streetscaping impacted by the Project will be reinstated. The Scarborough Junction Grade Separation Project takes into consideration pedestrians and cyclists in many ways, such as the incorporation of elevated sidewalks to reduce grades and are designed to City of Toronto and Accessibility for Ontarians with Disabilities Act (AODA) standards, which will improve pedestrian and cyclist movement. Where identified by the City of Toronto, we have maintained or improved cycling facilities, and have worked with the City to align the road design with City of Toronto Cycling Network Plan.

Work associated with the proposed multi-use crossing at Corvette Park is being planned in conjunction with the City of Toronto to align with relevant Official Plan policies where feasible, maintain the envisioned form and function of Corvette Park and to ensure this community asset remains intact. Section 2.4.14 of the City of Toronto Official Plan (2015) states that the urban environment should encourage and support pedestrian movement. Connections between the street network and other pedestrian walkways such as parks should be maximized. The multi-use crossing at Corvette Park will provide a new connection to Wolfe Avenue which increases connectivity between neighborhood streets and enhances pedestrian routes within the neighborhood. The Official Plan (Section 2.1.14) also states that grade-separated crossings should be provided at rail corridors where warranted. The new grade-separated crossing at Corvette Park will remove barriers to pedestrian and cyclist movements in the neighborhood while encouraging active transportation choices.

Currently, Stouffville line trains are able to stop at Scarborough GO station. With frequent two-way all-day service, this provides an opportunity for passengers to connect with Lakeshore East line trains. The renderings for the Scarborough grade seperation don't depict platforms.

Will Scarborough station include platforms for Stouffville line trains after the grade seperation?

Thank you for your interest on the Scarborough Junction Grade Separation Project and on the Scarborough GO Station. As part of the GO Expansion Program, a new track will be built on the Stouffville Rail Corridor to achieve the Metrolinx goal of providing two-way service on the Stouffville Rail Corridor south of Unionville GO Station. This new track was assessed and approved as part of the Stouffville Corridor Rail Service Expansion Class EA. Stouffville GO trains will continue to stop at Scarborough GO Station, and there will be platforms to enable this two-way service.

I would like to know the details. Is it mean that cars/ trucks cannot pass from Kennedy road to Midland road?

Thank you for your interest in the project. Please note that Havendale Road is an at-grade crossing to be altered as part of the Stouffville Rail Corridor Grade Separation Project.  

To facilitate two-way all-day service on the Stouffville Rail Corridor, Havendale Road is proposed to be closed to vehicular traffic crossing the rail corridor between Belgreen Avenue/Fulbert Crescent and Agincourt Drive/Stainforth Drive. Vehicles wishing to cross the rail corridor to access Kennedy Road and/or Midland  Avenue will be required to reroute to the next nearest crossing of the rail corridor, either Huntingwood Drive to the north or Sheppard Avenue East to the south.

Both tunnel and bridge grade-separated multi-use crossing are being considered as part of the Transit Project Assessment Process (TPAP) at Havendale Road to maintain pedestrian and cycle traffic.

VIA Rail Canada currently operates along the GO Lakeshore East line, through the proposed Scarborough Jct flyover. VIA is pursuing a High Frequency Rail (HFR) proposal which would potentially add further capacity requirements to the LSE line, or on other routes such as the Metrolinx Don Valley line (slated for conversion to a layover yard) and/or the Metrolinx Stouffville Line. Has Metrolinx confirmed VIA Rail Canada's current and future requirements for track capacity on each of these lines? Has this need been factored into Metrolinx's expansion program? Can intercity travellers be assured that Metrolinx will afford VIA the necessary track capacity for its own expansion plans?

Metrolinx has shared its plans for the proposed Don Valley Layover and Midland Layover facilities and the New Track & Facilities TPAP Project and the Scarborough Junction Grade Separation TPAP Project with VIA Rail as part of the TPAP consultation efforts. The new rail-rail grade separation through a tunnel traveling under the Lakeshore East (LSE) Rail Corridor will allow trains to freely pass without the need for stoppages, increasing travel speed and capacity on our rail lines. Metrolinx will continue to work with VIA Rail as they advance their planning for the High Frequency Rail Project. Metrolinx and VIA Rail are working together on this matter and will seek to maximize the public benefit of infrastructure investments.

During the first information session several properties along Aylesworth Avenue were to be impacted by modifications to the Scarborough GO station. I do not see any mention of that impact in this report. Have the plans been modified to maintain the current layout of the tracks in the portion next to the homes on Aylesworth Avenue?

Thank you for your feedback on the Scarborough Junction Grade Separation Project and how properties along Aylesworth Avenue may be affected by the Project. As part of the GO Expansion Program, a new track will be built heading north on the Stouffville Rail Corridor. This new track was assessed and approved as part of the Stouffville Corridor Rail Service Expansion Class EA in 2014. The new track alignment for the Stouffville northbound track may not be able to be accommodated in the space between the existing tracks and station building. As such, the GO Station building may be modified or relocated; however, the building will remain within the existing property boundaries of the Scarborough GO Station.

The Project design is not yet finalized, but Metrolinx has completed a conceptual design that identifies the maximum anticipated impacts from construction. While permanent works (such as new tracks) are expected to remain within the existing rail corridor, temporary disturbance to a portion of some properties on Aylesworth Avenue may be required to facilitate construction. This may require removal of existing fences and potential disturbance to backyards. The temporary construction area may encroach onto some properties along Aylesworth Avenue and may remain in place for up to 2 years, beginning as early as 2022. Individual property owners will be contacted by a representative from Metrolinx Property Acquisitions to discuss the specifics of potential impacts to the property. MX property acquisition will reach out following the completion of the TPAP phase, which includes approval for the conceptual design. It is anticipated that the TPAP will be completed in Winter of 2021.

In your GO Expansion Full Business Case, there aren't any trains that terminate near the Midland Layover (Scarborough GO/Eglinton GO). Where are those layover trains coming from? Is Metrolinx extending some of the trains to Scarborough GO/Eglinton GO?

Thank you for your inquiry about the Scarborough Junction Grade Separation Project and how the Midland Layover is planned to be used. Metrolinx has multiple layovers throughout the system, and not all are located at the termination of a line/service. Some existing examples include Willowbrook Maintenance Facility in Etobicoke, Bathurst St. Yard in Toronto, Henry St. Layover in Whitby, and Lewis Rd. Layover in Stoney Creek. The Midland Layover will provide multiple options for trains to be brought into service anywhere along the Lakeshore East and Stouffville Rail Corridors.
