Railroad riders expecting to pass through New York City’s Penn Station this summer should prepare for significant delays and even cancelations as the tracks undergo renovations.

When Amtrak shuts down several tracks for repairs in July and August, service could be reduced by up to 25 percent, Amtrak CEO Charles W. Moorman said at a press conference.

The work — which is scheduled to happen from July 7-25 and August 4-28, including weekends — will affect Amtrak, Long Island Rail Road, and New Jersey Transit passengers. Up to five of the 21 tracks at Penn Station will be closed at a time during repairs. A schedule of revised service is expected to be released within the coming weeks.

Moorman also said that Amtrak will continue to shut down tracks at the station for “an undetermined stretch next year,” according to the New York Times — although the disruptions should be for a shorter period.

“It’s a full replacement of all the complete timber steel, switches,” Moorman told press. “All of that is at a point where it needs to be renewed rather than us trying to stretch it out over a longer period of time.”

Penn Station is the busiest train hub in the country. About 600,000 people pass through the station every day and much of the tracks and infrastructure date back to the 1970s.

Two trains have derailed at the station since March, drawing particular attention to the aging infrastructure.
