RE: North Temple Trax/Frontrunner station. It looks like there is a 7-8 minute differential in time between unloading of the Frontrunner to catch the next Green Line Trax trains to the airport--otherwise you wait another 15 minutes. I haven't done this for years--is it doable to get from Frontrunner to the Trax station in 7-8 minutes, or do you just plan on catching the 2nd Trax train? Are there stairs to get from Frontrunner to Trax or is there something automated (if you have luggage)?
