NEW YORK (AP) - The busiest U.S. train station is a gateway to New York City - and a utilitarian labyrinth from the 1960s built in the basement of a basketball arena.
Pennsylvania Station was designed for 200,000 riders a day. It's now packed with about 600,000 and becomes a human demolition derby at rush hours.
All it takes to strand hundreds of thousands is a glitch on one of only two tracks to New Jersey under the Hudson River.
Decades after plans were made to expand the train hub, little has changed.
Vin Cipolla heads the Municipal Art Society that helped save Manhattan's Grand Central Terminal from demolition. He calls Penn Station "a disaster" that could be transformed if Madison Square Garden moved. The arena's permit has expired, and owners hope for a new one without time limits.
