WOODLAND PARK, N.J. — It’s going to get worse before it gets better at New York Penn Station.

Amtrak announced Thursday an ambitious plan that officials say will cost tens of millions of dollars to attack the problems that have plagued commuters at the nation’s busiest rail station over the past month.

Commuters can expect more track shutdowns this summer — and not just on weekends. Tracks also will be closed on weekdays as Amtrak accelerates a three-year program to repair the byzantine maze of tracks below Madison Square Garden in an attempt to finish the most critical work by Labor Day.

In addition to fixing the aging infrastructure, Amtrak also will address security concerns and how passengers are treated, the rail company’s chief executive said in a telephone conference call.

“The events of the past month have shown that we just have to step up our game there,” said Amtrak Chief Executive Charles W. “Wick” Moorman, referencing the recent derailments and resulting delays and crowds at Penn Station.

“We take our responsibilities as owner and operator very seriously,” he said, adding that it was “critical to make sure that we operate the station at a high level.”
