[1] Crossing over Yonge Street and what is now the Davisville Subway Yard, the loop continued northwest until Spadina Avenue, where it crossed Eglinton Avenue and turned west, eventually meeting up with the Grand Trunk Railway (GTR) railway tracks (now the GO Barrie line) just west of Caledonia Road.

Trains ran along this line until the late 1960s when a small part of the right-of-way was expropriated to build the Spadina Expressway, now Allen Road.

[3] Most homeowners adjacent to the line wished to buy the land to extend their backyards, complaining of safety issues, vandals, and lovers.

[3] Metro Toronto parks officials and York Mayor Phil White saw it as an opportunity to build a bike path.

Toronto Mayor William Dennison and his executive committee favoured buying portions of the Belt Line to expand roads and existing parks.

[3] Dennison told the Toronto Star that he opposed a continuous path along the Belt Line because "people have demonstrated they just won't use it", as well as echoing fears of the homeowners.

[3] One of the supporters of turning the rail bed into a bike path was alderman David Crombie, who was elected as mayor of Toronto soon after.

The trail then continues southwards through the Moore Park Ravine alongside Mud Creek, a small tributary of the Don River.
