For once, an A Line closure has nothing to do with an A Line failure.
The train to the plane has been shut down at 48th and Peña Station, according to Denver International Airport.
An RTD bus will take passengers to and from that stop and the airport.
The Denver Fire Department is responding to the fire at Peña Boulevard and Tower Road. There have been no injuries. No word yet on the size of the fire.
Update, 3:30 p.m.: Denver Fire says the brush fire is out and crews are mopping up hot spots. There were no injuries.
The RTD says the A Line is running between Union Station and 61st and Peña Station. A bus is taking passengers the rest of the way to and from the airport.
