This explains the fire alarm going off intermittently in B last night. The message kept repeating something like "An emergency has been reported in this building. Please stand by while we verify the emergency". It was universally ignored.
We landed at ATL in the A concourse around 7PM and flew out of B at 9 with no delays but the train was definitely not running when we were there (one was dwelling in A) and there were announcements to that effect in the tunnel. We weren't sure if the train caught fire again setting off the fire alarm or if the fire alarm going off stopped the train. I guess it was the later.
EDIT: reading the article, the fire happened at 7:30 and the entire tunnel filled with smoke quickly after that. We must have been down there just as it was happening because we noticed the trains stopped and the alarms but no smoke yet when we walked from A to B.

Not just the taxiway. The tower uses "dixie" in place of "delta" for all uses of the phoenetic alphabet for "d".
