Denver Broncos quarterback Peyton Manning is known for calling audibles on the line of scrimmage but now he will be known for being the voice on the train.

Denver International Airport Friday announced Manning will be the new voice in the train cars passing through the airport this holiday season, starting Friday and ending Jan. 2.

Denver Mayor Michael Hancock, whose voice normally greets DIA travelers, offered up Manning as quick substitute.

"For the holidays, I am handing off this very important duty of greeting visitors to our great city to someone known for the best audibles in the business," Hancock said. "Peyton Manning earned this call by going long in his efforts to take the Broncos to another AFC West championship. We'll be cheering on him and the team as they drive toward another Super Bowl!"

Manning's southern drawl is heard over a piano playing "Jingle Bells."

"Welcome to the Mile High City," Manning says.

Denver International Airport is the 11th-busiest airport in the world and the fifth-busiest airport in the United States.

With more than 50 million passengers traveling through the airport each year, DIA is one of the busiest airline hubs in the world's largest aviation market.
