Are those bridges already wide enough for a second track?
It seems like they've dialled back converting the at grade crossings north of the city. They'll probably just plow 2WAD service through and upgrade incrementally over the long term.
After the Barrie Line Double Track Enabling Project is done in Summer 2025 we should see some kind of update. Perhaps they'll just Double track all the way up to Aurora in one contract and finally get around to building Caledonia and Bloor-Landowne, etc.
Interestingly, we received notices that the hydro corridor that runs along the west side the Barrie Rail line between Davenport and just North of St Clair will be relocated at the request of Metrolinx.
According to Hydro One:
"The majority of the proposed tunnel would run underneath Caledonia Road at a depth of between 10 to 40 metres underground and would connect into new junction stations located at each end of the tunnel. A junction station facilitates the transition from overhead to underground lines. These sites would also serve as tunnel shafts for construction and access points for ongoing maintenance and operational needs."
This also frees up a lot of the land needed to build the proposed Earlscourt Station that was shifted to their 2035+ plan.
