UPDATE: Inter-Concourse Trains At Hartsfield-Jackson International Airport Working Again

UPDATE (4:20 p.m.): WSB-TV reports that after a shutdown of just more than an hour, the trains at Atlanta’s Hartsfield-Jackson International Airport are running again.

A computer error caused the shutdown at approximately 3 p.m. Passengers were forced to walk between concourses instead of taking the train, causing serious backups on the platforms.

It will take some time to alleviate the pedestrian traffic on the platforms, so please use caution if you are or will soon be at the airport.

ORIGINAL STORY (4:00 p.m.): The handy train line that shuttles passengers between councourses at Atlanta’s Hartsfield-Jackson International Airport has shut down, multiple sources report.

According to WingStats, an aviation company, it is taking people 30 minutes to walk between concourses B and C at the world’s busiest airport. The walkways between the terminals are flooded with pedestrians trying to make their flights on time. FOX 5 Atlanta retweeted an account of a person inside the airport that claims the tunnels are “blocked and hot.”

The Atlanta Journal-Constitution reports a computer error caused the shutdown at approximately 3 p.m. on Friday. Airport spokesman Reese McCraine says that work is underway to get the trains running again, though he is not sure exactly when they will be operational again.
