Football fans wait to go through security at the Secaucus Junction, Sunday, Feb. 2, 2014, in Secaucus, N.J. The Seattle Seahawks are scheduled to play the Denver Broncos in the NFL Super Bowl XLVIII football game on Sunday at MetLife Stadium in East Rutherford, N.J.
NEW YORK—Super Bowl ticket holders are turning New York City's Penn Station into a sea of color as they make their way to New Jersey for the game.

Fans wearing orange for the Denver Broncos and green and blue for the Seattle Seahawks have been crowding into the station Sunday. They've been trading shouts of "Broncos!" and "Seahawks!" as they wait for trains to Secaucus (sih-KAW'-kuhs), where they'll board trains for MetLife Stadium at the Meadowlands in East Rutherford.

Security is tight, with strict rules on what fans can bring into the stadium.
