Today when I was coming home from work, a group of construction workers got on the train and sat down.  One of them said, grumpily,


He then proceeded to complain about many other things, which leads me to believe that he was probably just having a very bad day.  All the same, perhaps he should be consulted before the Airport line opens.

Dang.  He's right.  Image from


  1. So, why is it called "the green line?" or "the blue line?" And where was that bus going? Does it have anything to do with the color green? I really don't know and would appreciate it if you would explain.

  2. I don't know the whole story, but here's my best guess:

    For a long time, UTA has had two TRAX lines, generally known as the Sandy Line and the University Line. On the map, they were colored blue and red, respectively. There were also a few trains called "Sandy University," which ran all the way from Sandy to the U. These were colored green on the map.

    With the opening of the two new extensions, the system has changed quite a bit. There are still three routes: one from Sandy to Salt Lake Central Station (the same as the old Sandy Line), one from Daybreak to the University of Utah, and one from West Valley City to Salt Lake Central Station. Apparently, rather than continue to name them after their destinations (especially since some of the destinations have changed), UTA has decided to call the routes by color instead. This is actually pretty common practice in urban rail transit, though many cities that do this have more on the order of six lines, making it much simpler to use colors. As the TRAX system continues to expand, they will use more colors.

    The assignation of lines to colors only has to do with the lines on the map; the same train car might run on the green line one day and the red the next. While the signs on the front of each train car are pretty easy to reprogram, it would be a lot of work to somehow mark each train car with the color of the line it's running.

    I admit it took me a few tries to remember which color of line went where, but now that I take the train every day, it's not a big deal.

  3. Ah, Thank you for the explanation. That helps a lot.
