Another photo from last week's after-work walk around the neighbourhood.
This is the Davenport Diamond, where two railway corridors cross each other a little north-west of Dupont St. and Lansdowne Ave. in Toronto's west end. This also defines the north-east corner of the neighbourhood I live in, the Junction Triangle.
The east-west railway corridor is owned by CP Rail, and the north-south corridor used to be owned by CN, but was recently purchased by GO Transit / Metrolinx. GO Transit is expecting to increase traffic on the north-south corridor, which runs from Union Station to Barrie, sometime in the near future. They're contemplating a grade-separation for this diamond: make one track go over or under the other one, so that trains on one corridor don't delay trains on the other. In fact, shortly before I took this photo, a northbound GO train had to wait a few minutes for a CP freight train to move through.
