Railroad siding near River Road

I have walked along the Capital Crescent Trail near River Road many times but I have never noticed the bit of railroad siding that remains in one spot.

See it? It is easy to miss, on the left about 5 feet above the trail and overgrown with vines.

Here's another closer look. This is the end of the siding, I believe this particular bit is to keep railroad cars from rolling off the end. Given how overgrown the rest is I wonder if someone pulled some vines away to make it more visible.

 I walked up the embankment to get a closer look and the rails are still there, going off to the right through the trees.  I removed some vines from a bit of the rail so I could get a better picture.  The cross ties are rotted and spongy, I thought the were going to break when I stepped on them.

The siding connected to the main line right around where the bridge that goes over River Road is.  There is a gravel road next to the trail and you can see a single rail embedded in the road.  Behind that is an open area that slopes up.  This was recently re-graded, the siding is a bit to the left and several feet lower than the current grade.

I walked back among the trees looking for more signs of the siding.  It is all still there, just overgrown with ivy and very hard to see.
