NEW YORK — Amtrak CEO Wick Moorman shed additional light on when commuters will know how much disruption the New York Penn State infrastructure project will cause commuters this summer.

Following questioning from the New York State Assembly's Standing Committee on Corporations, Authorities and Commissions at a hearing in Manhattan, Moorman told reporters that Amtrak will release its final schedule during the week of May 15.

Moorman, who offered apologies for the recent delays and issues at Penn Station, said commuters should expect "two multi-week outage periods this summer but that significant levels of service will continue to operate in the station" beginning in July. The CEO told reporters that 75 percent of scheduled trains in and out of New York would still run.

A preliminary report from Amtrak said a total of 44 days would be affected July 7 to 25 and Aug. 4 to 28. Moorman said there will be at least one more prolonged period of work in 2018.

He said that once Amtrak announces their plans, NJ Transit and the LIRR will be able to makes their own respective plans public.

Moorman said that work would be done during the Memorial Day, Independence Day and Labor Day weekends but not "heavy scale" work because "it would be difficult for us to get an adequate workforce." When the weekday work is being done work will go on "around the clock," Moorman said.

Most of the work will take place in the western side of the 112-year-old station, which Moorman called "absolutely vital" to stopping small incidents from becoming big problems for riders.

"Penn Station is the single-most difficult and complex place to do track work that I have seen with an extraordinarily complex set of tracks."

Moorman also announced another part of the rehabilitation program is moving forward: the creation of a new development entity that will bring in a private company to manage the concourse. Amtrak, NJ Transit, LIRR will be involved in the joint management and operation of the concourse.
