DENVER (AP) - Security wait times are back to normal at Denver International Airport following a backlog created by a problem with the airport's automated trains.
Wait times reached an hour earlier Friday, causing some people to miss their flights.
The trains that take passengers from the main terminal to their gates were stopped briefly Friday morning, likely because of a software problem. Passengers were funneled through one security checkpoint and some were bused to their concourses until the trains were able to start running normally again.
The trains were kept running manually for a time but they weren't able to run as fast, and couldn't move as many passengers as they normally do.
The airport is the fifth-busiest in North America.
