[1]: 77 The North Yonge Railways ran along Yonge Street from Glen Echo Terminal at the then-Toronto city limits through the municipalities of North York (Willowdale, Lansing, Bedford Park, Teddington Park), Thornhill (now part of Vaughan and Markham) and Richmond Hill.

The line was single-track with passing loops and ran almost entirely on the side of the road, with an off-street terminal at Glen Echo and some centre-of-street track in Richmond Hill.

[3] To restart service, the Townships of North York, Markham and Vaughan and the Village of Richmond Hill had acquired their portion of the line and contracted with the Toronto Transportation Commission to run it.

[1]: 45 Effective April 14, 1942, the TTC started night service to Richmond Hill at the request of the municipalities owning the line.

The reasons for the bus supplements were increased ridership, an insufficient number of radial cars and power shortages.

[1]: 77  The TTC had insufficient funds to replace the worn-out infrastructure such as rails and cars, or to double-track the line which was being considered.

At the end of the six months, North York Township advised residents that buses would be less expensive than rail vehicles to service Yonge Street.

At the time of the purchase, Hydro managed both operations under contract on behalf of local municipalities which owned the lines.

[6] When the North Yonge line closed in 1948, the cars were put into storage, and later scrapped by (Western Iron and Metal Co) or sold off.
