DENVER -- The RTD A Line was delayed 40 to 60 minutes in both directions Thursday morning because of crossing issues and a broken rail.
Trains that go between Union Station to Denver International Airport were running on a single track between the 40th/Airport and 38th/Blake stations because of a broken rail near the Central Park Station, RTD said.
A crew is working to fix the problem "as soon as possible," RTD said, adding riders should allow for extra time to and from the airport. It advised alternate transportation because of the cold weather.
A bus shuttle was put in place between Union Station and the airport.
Earlier Thursday, the A Line was experiencing delays of 10 to 15 minutes because of crossing issues at South Quebec Street, Havana Street, Sable Boulevard and Central Park Boulevard.
The Federal Railroad Administration has granted RTD a 90-day extension to to fix the crossing gates. The A Line has been run under a temporary waiver since it opened.
The line has been plagued by numerous delay issues since it opened in April. In October, it was revealed electrical problems and red flags with the design were raised before the line opened.
