Metrolinx has begun its last public consultation during the assessment phase of the GO expansion program, which will solidify the design of infrastructure across the region. The consultation began Nov. 27 and continues through Dec. 11.
The GO expansion will change how commuters will travel through the region, with trains every 15 minutes in all directions. Customers will have more choices in transit than ever before. The project also includes a revamped Union Station, with wide open platforms, level boarding and additional stairs and elevators to increase accessibility. These changes will expand on the long list of improvements made to the Union Station Complex in recent years and will accommodate the planned service increases and new electrification infrastructure and improve the customer experience.
With an increase from 1,500 weekly rail trips to 6,000, many more trains will travel on the network and all trains currently travel through Union Station. To ease the bottleneck at Union Station and facilitate train movements, layovers, which provide train storage and light maintenance, will be located throughout the system. These facilities will allow a quicker start to service each day and reduce the need to move empty trains through the system.
A total of three new layovers have been studied and after consultation throughout this year, the locations of Midland and Don Valley in Toronto, the Walker’s Line layover in Burlington, as well as the Unionville train storage facility in Markham were selected.
Grade separations are another key element that will help to unlock new service levels and increase safety and convenience for both transit and road users. Grade separations allow road users to travel seamlessly over or under the rails, without needing to stop for passing trains. With 15-minute service levels in both directions on core lines, grade separations ensure level crossings are not closed every seven to eight minutes.
Beginning in early 2020, Metrolinx has been consulting with the public and stakeholders around the region on local grade separations. Throughout the process, feedback has helped to develop a preferred design that satisfies the needs of impacted properties and businesses.
The last piece studied in this round is the electrification of the Metrolinx-owned rail corridors. Electric trains run up to 29 percent faster with 60 percent lower operating costs per kilometer. The service levels envisioned for GO Expansion are not possible without electric trains.
While electrification has been studied before, since 2017, Metrolinx has developed a detailed design and service plan for how increased passenger service will be delivered for the GO Expansion program in the future, including a mix of diesel and electric propulsion. According to the service plan, some locations will be served almost entirely by electric trains, some by a mix of electric and diesel trains and others by diesel. These proposed changes required a reassessment of potential noise, vibration and air quality effects as part of an addendum to the 2017 environmental project report. The findings of the updated noise, vibration and air quality assessment reports can be found online.
TPAP overview
GO Expansion consists of many different projects. The largest piece represents all the work that is required to enable service levels identified in the GO Expansion Full Business Case, including new trains, facilities, signals, systems, as well as the maintenance and operation of the system for years to come. This transformation will bring fundamental changes to GO Transit’s seven operating rail corridors. It will result in the implementation of new rail and electrified track that will be laid to allow for the more frequent and efficient movement of trains.
That leads to the ‘Transit Project Assessment Process’ – or TPAP. TPAP is a focused impact assessment process created specifically for transit projects.
There are three TPAPs undergoing public consultations now. They include New Track and Facilities, Scarborough Junction Grade Separation and Stouffville Rail Corridor Grade Separations.
Two TPAP addenda are also taking place, for which there are two rounds of public consultations. They are Network-Wide Structures Project – an addendum to the Barrie Rail Corridor Expansion TPAP 2017 – and an addendum to the GO Rail Network Electrification TPAP 2017. The proposed changes to the Union Station Trainshed, are being addressed through a heritage approval process.
