Huh, I'd never heard of that station, but looking at a map I see that you are right - there is station-sized island between the tracks at
2200 West, North Temple, complete with crosswalk and some utility boxes already in place. I had always assumed that place was a failed experiment to test growing grass between the rails, though I guess it did prove that TRAX trains don't usually set dead dry grass on fire...
That is an interesting location for a station. It would be less than 2000 feet away from the 1940 West station, which is closer than any other two stations on the Airport Line. But since it would be alone on the west side of I-215, I can see the wisdom of wanting a station there. Are there any firm plans of future developments in that area?
