Caption: The City of Montreal seems perpetually under construction. One of the biggest projects is the rebuild of the Turcot Interchange. It requires the relocation of the Canadian National tracks as a key part of the project. All four tracks will be relocated through Turcot. To date only one track is open. That track is the siding known as Track 29 that was/is used for block swapping. The train is CN #149, the Port of Montreal to Chicago container train, and its power backed into the new track to retrieve cars left for it by #121 the Halifax to Toronto container train. Complete cut-over to the new line is scheduled for August 2018.
