ABCs of the 97 Yonge bus service not for kids

The familiar 97 bus which used to take passengers all the way up Yonge Street from downtown to Steeles Ave has been turned into a kind of alphabet soup by the TTC. They say it is for a good cause. There is serious construction on north Yonge. The changes are intended to make things run smoother. But it means the 97 bus no longer turns into St. Clair Station.  Last Monday the TTC split the 97 into two separate north and south services. Buses on the northern section now operate from Steeles Avenue to Lawrence Station via Yonge Street, on a 97C (Steeles-Lawrence Station) branch. On the southern section, seven day a week service is now operated on the 97A (Davisville Station-York Mills Station via Yonge Blvd) branch. Monday-Friday peak period service will be operated on the 97B (Queens Quay-York Mills Station) branch. Service between Davisville Station and St Clair Station, which previously operated in the midday from Monday to Friday has been removed. Service levels will change slightly. An apple for the teacher please. TTC map. 
Escalators at York Mills Station  
Still on Yonge Street, Jaye Robinson (Ward 25) is passing on a TTC note that both escalators at York Mills subway station are out of service until the Fall for renovation. Oh joy!  The old trundlers have passed their 25-year life and need an overhaul.
