This Streetcar is not named desire. It is named the Queen Streetcar and is numbered 501 like a pair of jeans.
Riding up and down Queen is pretty awesome, especially on one of these rickety cute trams that brave some of the harshest winters in any large city anywhere in the world. They're good at ploughing their way through snow, but get pretty cold in the winter. I've ridden on this thing in both winter and summer and I can say that even the most sweltering of days in the summer is preferable to the bitterness of the long dark winters here. The system is actually quite thorough for the vital parts of Toronto, and there are underground trains, buses, and these awesome streetcars. Prices are pretty decent.
I've got 99 streetcars but none are as good as the 501.
