I haven't seen the new signs yet, but it's definitely a good hike from one end to the other. Whenever I have a delayed flight, I sometimes walk the transportation mall as a means of exercise and a way to kill time...that's a workout that can't be beat!

Quoting Mikey711MN (Reply 8): Somewhat relatedly, anyone know what the backup plan is if the terminal tram at DEN ever failed? Has it ever?!?
If you notice, every airport train system runs two different tracks for efficiency ... one train to take passengers in one direction, the other to take them in the other.
In an emergency situation, a single train can run both directions ... it would just be vastly slower service since it can't reverse until the end of the line, or somewhere there's a switch so it can cutover to the other track.
It's not much different than managing a subway when similar problems crop up.
In the case of a total outage (ie: power goes out, something like that) I would imagine they would have to bus people across the tarmac, kind of like the shuttle bus that takes people to the Comair terminal at CVG.
ATL's design was pretty forward at the time, allowing for pedestrian traffic in addition to the train system. Not many airports that have added trains since then have opted for the same, for some reason.

I remember reading an article about the design of the current ATL airport and the original plan called for only a train and not having the option of using an walkway in between. The airlines ultimately complained about this and pushed for the walkway in case the train broke down...smart move it turns out.
In the case of some airports such as TPA and MCO, the only way between the landside and the airside terminals is via the elevated shuttle system. There are two tracks, so whenever one train goes down, there is a back up. There is a walkway between the tracks, but it is only used in the event that both trains brake down. In the case of MCO, it's an especially long journey to have to make by foot.

I remember a few years back hearing that the train system at DIA did go down, and it was for a period of hours, IIRC. Anyone trying to get to/from the Jeppesen Terminal and Concourses B & C had to be bused. You can imagine that this was a major headache, especially being that this was not, of course, a scheduled shutdown. Scores of flights were delayed throughout the day, because of the lengthy time it took to get passengers out to the concourses. Actually, DL & EA demanding that ATL provide an alternate means for passengers to access the concourses was genius, in retrospect. The space between the tracks was already planned to be there, so it was a relatively simple addition (or correction, most would agree). Thankfully it came at a point early enough in the planning and design stage.
A couple of the original designs of ATL's Midfield Terminal were vastly different from what was ultimately built. One dramatic difference is that more than one offered an at-grade train system? It would have been exposed to the elements. What I recall reading is that after a freak ice storm in DFW that paralyzed its people mover system, the architects went back and devised a way to submerge the train @ ATL, so that weather would not be a factor. Again, genius.
While the train @ ATL may go down from time-to-time, it's typically not for more than several minutes, and that Transportation Mall is always available. Thankfully.
I haven't seen the new signs, either, but will check for them next time I fly to or via ATL.

A while back when I was at TPA one of the trains was broken, and they still opened up the outdoor emergency walkway between both trains.- Absolutely awesome, you get to hike over the road ways, parkinglots, past tarmac, into the terminal. It's a shame they dont open it up to the public and put out benches- it would make great spotting.
