Kitchener Line GO Expansion

Corridor Improvements

Corridor work along the Kitchener Line is part of the GO Expansion program, which will transform GO rail from a rush-hour service to a more frequent, two-way, all-day rapid transit experience. Foundational work for a second track, as well as other corridor improvements, will make it possible to deliver increased two-way, all-day service.

Halton Rail Expansion

One of the next steps toward delivering faster, more frequent GO service is separating passenger trains from freight trains.

Today, much of the rail corridor between Bramalea and Kitchener GO Station operates primarily on a single track, limiting the frequency and flexibility of two-way GO train service along the corridor. Metrolinx is purchasing a 26.2-kilometre section of rail corridor, currently owned and operated by CN Rail, to fix that problem.

More than 40 kilometres of new track will be added along this section, allowing passenger and freight trains to operate independently. Work will also include upgrading signalling systems, bridges and platforms.

Once complete, customers will benefit from:

Two-way, all-day hourly service to Kitchener and Guelph
Two-way, all-day 30-minute service to Mount Pleasant GO Station
Expanded seven-day-a-week service

This work is currently in design phase. For more information on project phases, please check out our project lifecycle page.

Highway 401 and 409 Rail Tunnel

Metrolinx constructed twin tunnels, less than three metres underneath Highways 401 and 409 – all without disrupting the 21 live traffic lanes directly above. Given it is one of the busiest sections of highway in North America, digging approximately 180 metres per tunnel was a unique challenge.

With major construction substantially complete, communities are one step closer to more service along the Kitchener corridor.

The Highway 401 and 409 Rail Tunnel project is part of the GO Expansion program, which will transform the Kitchener line from a rush hour commuter service to a more convenient transit experience with frequent, two-way, all-day rail service.

As the region continues to grow, more trips along the Kitchener line will open up opportunities for those connecting to jobs, family and what matters most – helping them get to where they need to go better, faster, easier.

Adding Track

We've been adding track along the Kitchener Line, in preparation for increased service levels planned as part of the GO Expansion program.

In 2018, Metrolinx completed the installation of a fourth track from Nickle Street to Black Creek Drive.

Now, a new approximately 2.5-kilometer section of track, will be installed from Lansdowne Avenue to Dupont Street to increase capacity on the Kitchener Line.

GO Expansion will offer more frequent service during middays, evenings, and weekends – giving customers more flexibility to schedule what is most important and everything else in between.

West Toronto Railpath Realignment

To accommodate the Bloor GO/UP Station Improvements Project, Metrolinx must realign the Railpath further east. A phased approach to construction is in place, closing only certain segments of the Railpath at a time, while maintaining access wherever possible. This strategy is intended to preserve the community’s ability to use the Railpath where possible.

Electrification

How do we take a rush hour commuter service to the next level? It’s about more than just the number of trips. Using electric trains on sections of the Kitchener Line will allow faster trains to transport you and will offer all-day trips, going two ways, as quickly as every 15 minutes.

Going to Pearson Airport? get there faster, easier and greener with electrified UP Express service planned as part of GO Expansion.

Electrifying GO rail corridors is a multi-year project and we are committed to working with residents across the Greater Toronto and Hamilton Area throughout the process.
