Jerri Williams, spokeswoman for SEPTA, said Philadelphia's Broad Street Line can transport 10,000 to 11,000 passengers to an Eagles' game in half an hour.
It would take approximately three hours to clear the Sports Complex area of a crowd of 30,000, with each train holding 800 to 1,000 people and leaving AT&T station every five to eight minutes.
"Any public transportation system only has so many trains that can operate at the same time," she said.
She hesitated to "bring up bad memories," but said last week's snowstorm, which sent a rush of people home at midday, and the 2008 Phillies World Series parade, which packed Regional Rail lines to capacity, evidenced similar transit issues.
For both Williams and Katz, the crowds, the travel headaches, the one-sided game were still worth the Super Bowl experience. "I wouldn't trade it," said Katz, whose flight home to Denver was canceled due to snow Monday, adding insult to injury. He considered spending his extra night at the New Jersey Devils hockey game in Newark.
"I thought about getting on another train," said the Super Bowl ticket winner, "but decided I shouldn't push my luck."
