After seeing the aerial maps of the New York City Subway system and Portland’s Rail system, I decided to try it out on my home city of Salt Lake City! Granted that at the end of the year, it will have three light rail lines, one street car line and one commuter rail line it is even simpler than Portland’s at this scale. (Not pictured in this photo is the Sugarhouse Streetcar line). But seeing as when I move to SLC two years ago, the green line in the lower left corner and the purple line (Frontrunner commuter rail) from downtown to the right side of the picture didn’t even exist yet, this system is making a lot of progress in a very short time.

Transit Maps says:

Not a lot to add to this, except to agree about the rapid progress that SLC has made with its rail transit. Now, if only they’d fix their darn maps…
