NJT riders who travel to Hoboken or Newark Penn Station and continue their trip to Manhattan via PATH trains will have to cope with shutdowns on weekends all summer. According to PATH, the shutdowns are necessary to facilitate the installation of Positive Train Control (PTC) equipment, which Federal regulations require for federally-regulated rail systems satisfying certain criteria; the installations are supposed to be completed by the end of 2018, although extensions are possible. PATH had similar closures in 2016 in the first phase of PTC installation. In 2016, PATH operated a special bus service between downtown and midtown Manhattan for passengers who could not travel to or from their desired destination; this year, instead, PATH will provide two-trip Metrocards so passengers can use the subway or regular NYC Transit buses instead. The special Metrocards will have to be used the weekend they are issued.

This year, the first phase of closures will take place the weekends of May 19 and July 7, when the World Trade Center and Exchange Place stations will be closed. Information in published accounts and on the PATH website is incomplete at the time of writing, but it appears that during these weekends PATH trains will operate on two routes: between Newark and Journal Square, and between Journal Square and 33 St, via Hoboken.  Passengers can receive the free two-trip Metrocard at the 33 St PATH station.

PATH's website does not appear yet to have the schedules for the remaining closures, but according to reporting by Patric Villanova in the Jersey Journal, the "uptown" Manhattan PATH stations on the 33 St PATH line will be closed on weekends between July 14 and October 28. On Saturdays, PATH will provide direct service from Hoboken to World Trade Center, which does not normally operate on weekends; but on Sundays, the only way for riders to get from Hoboken to World Trade will be to take a Journal Square-bound PATH train at Hoboken and transfer at Grove Street, often a lengthy journey. Not specifically announced yet, but apparently the free two-trip Metrocard would be available at the World Trade Center PATH terminal on these days.

Not found on the PATH site, but reported in the Jersey Journal article: it is said that on three Sundays, Sept. 15 and 22, and Oct. 13, the Hoboken PATH station will be closed completely.

When New Jersey PATH stations are closed, PATH tickets and passes will be cross-honored on the Hudson-Bergen Light Rail, apparently so riders can travel between Hoboken, Newport, and Exchange Place PATH stations; it's not clear whether the cross-honoring would be in effect outside this zone.

Service will apparently be normal on the Labor Day weekend.
