Proposed Infrastructure & Studies

New Track & Facilities - Proposed Infrastructure & Studies - Public Information Centre #2

To support the expansion, Metrolinx has identified various infrastructure requirements including track and switches, layovers/storage yard, and electrification to achieve established service level targets across the network.

 

Proposed Rail Layover and Train Storage Yard Facilities

Layover and storage yard facilities are essential for train operations. They typically include train storage, cleaning and serving, waste management, crew services, and track, switches and utilities.

Layover and storage yard facilities are necessary to achieve the targeted GO expansion service levels by:

  • Reducing long-distance non-revenue trips;
  • Accommodating train storage during off-peak hours;
  • Allowing trains to be routinely serviced and cleaned;
  • Providing flexibility for trains to operate more seamlessly across the network; and
  • The proposed locations are strategically located throughout the GO rail network to maximize service efficiency.

Updates from Round 2

  • In Round 2 of public consultation, we added information about the associated impacts and proposed mitigation for each of the previously presented facilities and revised the design of the Don Valley Layover in the City of Toronto. We also presented the additional site for a proposed layover facility at Walkers Line in the City of Burlington on the Lakeshore West Corridor.
  • In Round 1, we presented the preliminary designs for Beach Layover, Unionville Storage Yard, and Don Valley Layover.

Proposed Track, Switch Locations & Platforms Across the Network

As part of the GO Expansion program, Metrolinx has identified various infrastructure requirements to achieve the established service level targets across the network. Required infrastructure includes new tracks within existing Metrolinx rail Rights-of-way (ROW), modifications or upgrades to existing tracks within existing Metrolinx rail ROW, and new platforms at existing GO Stations.

A number of switches are also are required within the existing track beds along a number of GO rail corridors. A switch enables a train to be guided from one track to another at a railway junction. Switches are needed to allow trains to easily move across the network, providing increased service. Approximately 150 new switches are proposed across the network.

Proposed Thickson Road Bridge Expansion

The existing rail bridge at Thickson Road in the Town of Whitby is to be widened to accommodate a new third track extending from the Whitby Maintenance Facility to Oshawa GO Station, within the Town of Whitby.

Proposed Electrification of the Lower Richmond Hill Rail Corridor

Electrification of a portion of the Richmond Hill Corridor north to Pottery Road is required to reduce rail congestion, allow trains to turn back and reduce idling and dwell times at Union Station. Bridges on the Richmond Hill Corridor that require Bridge Protection Barriers due to electrification include: Eastern Avenue Bridge, Don Valley Parkway Ramp, Dundas Street Bridge East, Gerrard Street East Bridge, Riverdale Park Pedestrian Bridge, and DVP to Bayview Extension Bridge.

Key Preliminary Design and Construction Commitments

Following the TPAP, the proposed infrastructure will move into the detailed design and construction phases. During these phases all applicable regulations, permits, approvals and best practices will be adhered to.

Studies, Impacts, and Mitigation

What are Environmental Studies?

Environmental studies are important components of a TPAP. Along with public feedback, they inform the Draft Environmental Project Report (EPR) that becomes subject for public review and the Minister’s approval.

These studies look at existing conditions to assess potential impacts from construction and operation of the proposed infrastructure and future train service, recommend mitigation measures/monitoring commitments, and provide key information for concept designs.

The following environmental studies have been completed or are underway for the Project:

  • Air quality;
  • Archaeology;
  • Cultural heritage;
  • Electromagnetic fields (EMF) and electromagnetic interference (EMI);
  • Hydrogeology and groundwater;
  • Natural environment (including species-at-risk);
  • Noise and vibration;
  • Socio-economic and land use;
  • Stormwater management;
  • Transportation and traffic;
  • Utilities; and
  • Visual/aesthetic.

To read highlights from the preliminary impact assessments and proposed mitigation measures for the proposed rail layovers and train storage yard facilities, go to the Proposed Rail Layover and Train Storage Yard Facilities section.

Completed full study reports will be made available once completed.

Operational Air Quality and Operational Noise and Vibration studies are being undertaken as part of a separate process. Please visit the GO Rail Network Electrification Addendum project website for more information.
