I happened over to NJT's website, and caught this notice about service on the PVL. Train 1621 (the 1:56 from Hoboken) will only run as far as Pearl River, with a transfer to a bus to Nanuet and Spring Valley.
The work (scheduled to take three weeks, so I figure around a month or so) is supposedly for the installation of switches for one of the new passing sidings.
Looks like the end is finally in sight (though still in the distance) for the work along the PVL.
