Problems on the Atlanta airport train generate “pandemonium”

() –– A computer problem with the train that transports passengers between concourses at Hartsfield-Jackson Atlanta International Airport caused bottlenecks and confusion as people rushed to their gates at the world’s busiest airport Monday morning.

Shortly after noon local time, the airport said in a statement that its train had returned to normal service “after experiencing a computer issue” on Monday morning.

Social media posts about the situation described a chaotic scene.

“ATL airport is chaos with the train stopped and masses of people waiting in the underground corridor between the concourses,” said a post.

The airport said airport and airline employees, as well as additional ground support, “helped passengers navigate concourses to reach connecting flights, baggage claim and gates,” while that train service was reduced.

There is a passenger walkway connecting the concourses.

Keagan Ilvonen, 33, managed to board his flight on Monday, but described the scene after security checks as a “madhouse.”

“There was no staff to give instructions or anyone to give information. Just people coming off the escalators to the above-ground train area,” Ilvonen told .

“Honestly the worst congestion and worst people handling I’ve ever seen at an airport,” Ilvonen said.

Tiffany King, 27, said in a message to that “staff were yelling at people to walk forward, but we couldn’t because there was a crowd that had stalled. It took me an hour to get from door B to door C.”

The automated train system has been transporting passengers through the airport since 1980. More than 250,000 passengers passed through it every day in 2018, depending on the airport.
