Trains At DIA Halted Due To Fire Alarm

DENVER (CBS4) - The trains at Denver International Airport were temporarily out of service Wednesday afternoon following a fire alarm.

Passengers were being taken by bus from Concourse A to Concourses B and C while the trains were being worked on.

Just after 4:15 p.m. DIA tweeted that the train service and TSA screening was back to normal.

It's clear why the fire alarm was activated.
