Another mishap temporarily shut down the new AeroTrain service at Dulles International Airport.
This time the culprit was a broken water pipe that flooded the platform area of the A station Sunday afternoon, according to the Associated Press.
Airport officials said the impact was limited. Passengers had to use the airport's old buses, known as "mobile lounges," to get to their gates, but it's the latest in a series of hiccups that have interrupted the $1.5 billion underground train service.
On its second day of service Wednesday night, operators detected an open door alarm while a train was in the tunnel. It was taken out of service for more than 30 minutes, causing a ripple effect that resulted in six passengers missing their connecting flights. Seems a firefighter left the door open by mistake while responding to an unrelated call.
Once again, passengers were bused to the terminal while the problem was being investigated.
The train system is touted as the future of ground transportation for air travelers. All aboard?
