Streetcar improvements. Very cheap, and would improve image of TTC. For example, on routes with high frequency, the focus should be keeping an even spacing, as opposed to keeping vehicles on time.
Couldn't agree more. One thing I hate about travelling by streetcar is having to wait at the stop a very long time only to have literally 4 or 5 streetcars arrive at the same time. Also, as with subways, I really doubt anybody pays attention to streetcar scheduling.
