I've checked the satellite imagery on ESRI Basemaps, Google Maps, & Bing Maps (they may however all be from the same source) and all show 5 tracks through the area in these^ photos but only 4 continuous lines. One track stops just North of Queen St and another starts on the opposite side of the corridor.
Hopefully this project will add 2 more lines on the North side of the corridor and realign the existing tracks into 5 continuous tracks giving 7 continuous tracks: Milton 2-way, Kitchener up-slow, Kitchener down-slow, Kitchener up-fast, Kitchener down-fast, Barrie up, Barrie down.
