The railroad was connected to the Seashore Branch with a connection right at the bridge over the Shrewsbury River, and had their own locomotives. the book "The Henry Hudson Trail: CNJs Seashore Branch" has a picture of the locomotive running light over the bridge and notes it as the last rail move out of Sandy Hook, i think the date was 1948. Most of the ROW is from what I have gathered, the southbound lanes of Hartshorne Drive, the main road out to the fort. There is one area where you can see where the tracks looked to have taken a different route, but basically most of the Southbound lanes are the route. Ive seen pics where the power lines roughly parallel the tracks.
There are a few spots out on the hook itself where you can see/tell that there was tracks at one time, either like out in the parking lot where there are still rails in the ground to spots where there is a hump in the road and a fill on either side of it. Seems like there was a good amount of trackage out there at one time.
In that big parking lot, I think it is parking lot H, on the west side of it, (as if on your way to Officers Row) there is a big brick building that to me, sure looks like it could have been an engine house.....
On the RR, "believe nothing you hear and only half of what you see"
