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
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
