Nice, shiny, new!  Already starting to get popular, the cars at times are full!  Time to add the third or middle car instead of running it in pairs.  \n\nA couple of things that really bother me about this train.  It's the first train system I've seen that does not have posted instructions of where to go in an emergency.  \n\nUsually on a Light rail or Subway type of train, they have banners posted on how to open the door and where to go depending on the type of track the train is on.\nWhat do you do if there's a fire?  What do you do if the train looses power and stops?  In the heat? There is absolutely nothing to inform you of this at PHX. The SkyLink at DFW has stairways to get off of the elevated track bed, PHX does not. DFW has the same brand and model of train, Bombardier.  \n\nThe T-4 station faces the Southwest Airlines ramp on the south of the terminal.  During Southwest's busy times, the station smells like exhaust.  Probably not a problem if you're in the station a short time, but there are people that work right there.  They have station monitors to help newbies, they are sitting there and watching or mingling with travelers that need direction, for hours at at time. And you have the janitorial people there keeping that expensive floor clean.
