partial implementation in 2025 and 2026 and full completion in 2032. The project entails the electrification of over of track, including of new track. Proposed frequencies In 2022, Metrolinx estimated that with GO Expansion, GO Transit would have the ability to run up to three times more trains than the 3,500 trains per week it ran in 2019. The busiest routes could operate between 8 and 18 trains per hour. Trains at GO stations such as Exhibition, Bloor and East Harbour could have a frequency of every 3 minutes and a 5-minute frequency at stations such as Burlington and Pickering. Evening and weekend service could be as frequent as every 6 to 15 minutes. The following more modest frequencies were projected in 2015. Two-way all-day service GO Expansion will see many sections of GO train lines receiving two-way all-day service. Sections proposed to get two-way all-day 15-minute or better are: Lakeshore West line between Burlington and Union Station Lakeshore East line between Oshawa and Union Station Kitchener line between Bramalea and Union Station Barrie line between Bradford and Union Station Stouffville line between Unionville and Union Station Sections proposed to get two-way all-day 30-minute service are: Kitchener line between Mount Pleasant and Union Station (every 15 minutes in peak period) Sections proposed to get two-way all-day 60-minute service are: Lakeshore West line between West Harbour and Union Station (already in effect since August 7, 2021) Lakeshore West line between Hamilton GO Centre and Union Station Kitchener line between Kitchener and Union Station (every 30 minutes in peak period) Barrie line between Allandale Waterfront (Barrie) and Union Station Stouffville line between Mount Joy (Markham) and Union Station Peak direction service Go Expansion will also see more frequent weekday, peak-direction service on the following routes: Every 15 minutes on the Lakeshore West line between Hamilton GO Centre and Union Station Every 15 minutes on the Milton line Every 30 minutes on the Barrie line between Allandale Waterfront (Barrie) and Union Station Every 15 minutes on the Richmond Hill line Every 20 minutes on the Stouffville line between Old Elm and Union Station Express service Stations between Oakville and Hamilton on the Lakeshore West line, between Bramalea and Kitchener on the Kitchener line, and between Pickering and Oshawa on the Lakeshore East line are proposed to receive express service to and from Union Station.
