I love the new strategies from TTC in an effort to help congestion of the streetcar system. A proof of Payment system makes it a lot easier to get on and off. The only problem is with the potential lost in revenue from fare. But in GO transit, this system has mainly worked, so it is mainly a system of ironing the kinks for TTC.
In another note, the new streetcars are spacious in terms of standing room. Which is nice.
