<Midnight Tram to Humber, PHOTO – Uwajedi/flickr>  TORONTO has 8 well-used streetcar lines, the largest network in North America.  For tourists, one of the best is the #501, which runs from Neville Park in the Beach to Long Branch in the west end.  Most of the trackage has been rebuilt over the past 5 years.  A new fleet of streetcars will soon make their debut.
