A broken power cable left 80 train passengers in Denver stuck on an overpass around 50 feet in the air Tuesday, officials said.
The A line to Denver International Airport lost power at around 3:21 p.m. local time, the Regional Transportation District said.
Passengers on the stuck train were stranded for two hours before they were walked down the elevated track to waiting buses, officials and NBC affiliate KUSA reported.
The transportation district said a cable that provides power to the train broke. It was the third time in a week the A line lost power, according to KUSA.
"This is incredibly frustrating and we know it," RTD spokesman Nate Currey told the station. The 23-mile A line is new, and opened on April 22.
