DENVER (CBS4) – If you are flying out of Denver International Airport Friday morning, getting there extra early is encouraged. That’s after a circuit breaker caused four of the underground trains to lose power overnight. Huge lines of travelers waiting to get to their concourses were seen at 8:30 a.m. inside the airport as a result.

About 200 people were on the trains at 12:30 a.m. when it happened, and no one was hurt. They were stuck in the trains for about 4 minutes. Then emergency personnel had to start escorting people on foot through the train tunnels.

Although some of the trains are apparently still running, one hour delays for trips from the terminal to the concourses, or longer, are to be expected early Friday morning.

At least one plane’s departure was delayed while the crew waited for the travelers who were slow to arrive at the gate due to the train issue.

Airport officials say they plan to have the problems repaired by mid-morning, and apologized on Twitter, writing “We wish a walkway to the concourses was created when the airport was built 26 years ago. However, issues like this are very uncommon on the train to the gates. We apologize for the delay during maintenance.”

On Thursday the airport ran into issues when the FAA issued a ground stop due to stormy weather in and around the Denver metro area.
