GO Transit

[Bytor]

The CN Halton Subdivision is a main artery for freight traffic and is important for both CN operations
and the overall Ontario economy. Project development work conducted by Metrolinx determined that
additional track capacity will be required to deliver the proposed service increases. The corridor would
consist of three and four track segments, with two tracks primarily used for freight traffic and the
remaining track(s) more utilized for passenger movements; although the dynamic nature of trains
sharing a corridor mean that all tracks are available to all traffic when required. Train meets will typically
be scheduled at locations with two passenger tracks; however, co-production (operating both
passenger and freight trains on the same set of tracks) will also be used to enable train meets in
constrained portions of the network.

For what it's worth, Metrolinx believes the 3-4 tracks in the corridor west of Bramalea can meet frequency requirements. That includes 15 minute peak direction and 30 minute 2WAD service to Mount Pleasant GO.

The three tracks only go to Mount Pleasant, which is why hourly service has stopped there and gone no further. And even then there are big gaps and it's never been hourly all day long.
