I didn't do much planning and just drove straight to where I knew they were at as they've been here since I was a child.
Here is a map of the area in the photos.

Fully exploring the line is a little rough since the only access I am aware of is here. a 50mph stretch of Route 47.

I headed down the line that the camera is pointed at. I didn't get far.
Just past the intial growth it opens up into a mini little water crossing. This doesn't look built like this and nature has taken its course and eaten away any pipe that might have been under this along with land to divert water under the tracks.

I walk ahead to the brush line turn around for this shot looking back where I came from.

Crossing the street and checking out the other side you're looking at this. Lots of growth.

A little further down

It then opens up to a short little rail bridge. I decided to cross it.

And then I got stopped in my tracks (rimshot). This has been washed out over time. First gap was about 4 feet, second gap was about 4 also, then the 3rd gap was 5-6ft. Too risky to attempt a crossing. This is tidal water, no telling how deep it is.

I'm going to go through the maps and see if I can intersect this old line somewhere else and go do some more exploring along it.
