I need to say this, the Leslie bus divide at Sheppard (51A/151) is so misinformed. Constituents were complaining to Shelley Carroll about the delays caused to the 51 by Line 5 construction on Eglinton.
That's over.
Their complaint was that all they wanted to do was access Line 4. This is very shortsighted however, considering that the opening of Line 5 will significantly change travel patterns, and this linear transfer will eventually become resented by the very same people.
The bald headed (Service Planning) gentleman in a suit at the Leslie Station Open House said to me that passengers counts show many people being inconvenienced travelling from south of York Mills to north of Sheppard. [Many people transfer at Lawrence.]
It's an infrequent bus, and I highly doubt 51As and 151s will hold for transferring passengers. The most congested segment on Leslie is between Esther Shiner and York Mills, the joint section which will cause the 151 to be just as unreliable as the 51A. I tried to fight it...
As a ~20 year constituent, the 51A should continue north to loop around Ravel (Finch), compensating for the TTC's reluctance to extend the 169A to Leslie. The 151 shouldn't go south of the 401 ever - it should serve the new towers in the former Canadian Tire Distribution Centre lands between Leslie and Bessarion (Burbank).
