What are the white ties?

Hi;
I've been finding these white rr ties everywhere in NY and NJ (and assuming they're everywhere else too) using Google Earth.
I measure distances, look for CC boards, and other reasons they exist, but have found nothing.
Can someone tell me what these are for?

The image below was captured using Google Earth just east of Selkirk yard and CPSK.

Here's another image; this one in Teaneck NJ on CSX River sub at West Englewood ave, a few feet south of the pedestrian tunnel under the tracks.

Thanks for your help.

The only thing I can think of is those are concrete ties. The mbta here in MA had a giant problem with them and replaced all most all of them I think.

I believe that CSX marks culverts with them.

they look kinda bright to be concrete.

Right, they mark where water crosses under the tracks.

Wow!
I never thought of that. I guess it makes sense; if heavy rains cause underground streams to overflow, tracks could be washed out or "dips" could form where the culverts collapse.

It's more for engineering and maintenance dept to find their culverts easier... it's same thing with roads. NYS have small yellow rectangle signs set up off the shoulder at where culverts are.

Painted more than my share,back in the day,on the Seaboard and then CSX. You'd repaint them every year during your regular trips making track inspections.

So that's what those yellow triangles on the road shoulders are. I have done a lot of running in NY, and see them all the time. I had thought they were survey markers.

You mean they're not just ties made from white wood <g>
I just found a set on the River sub between CP66 and CP69 where I can actually see the culvert and the water on GE.

There were days when I wished there was white wood.
