The Pineaire section should see little disruption at all. It's already double tracked in this area.
From Farmingdale to Ronkonkoma, there seem to be about eighteen grade crossings. I fear the day that someone driving a heavy truck of molasses, oil, or steel crosses in front of a train, causing a massive collision or wild derailment. The recent Brentwood crash involved only a medium-weight automobile. That the NY Department of Transportation built a 12-lane bridge crossing Wicks Road but has not yet built a two-track bridge at the Main Line's crossing two miles south of I-495 remains the wrong decision.
-----
Wicks Road (Fifth Avenue) appears to be the widest road crossed at grade. Or is there a wider one? Or is there a busier grade crossing?
-----
I count five grade-separated crossings in that stretch:
NY 110 at Republic.
NY 231 at Deer Park.
Sagtikos Parkway
NY 454 Veterans Hwy
County Rd 29 Ronkonkoma Avenue

Which was the first location to be separated?
Thanks.
