N & W coal loading piers 1924

I like to post old railroad and industry photos while I am working on my models to keep the blog fresh.  This photo shows the N&W loading piers # 2-4.  Pier number 3 bunkers four steamers simultaneously.  Pier number 2 loads 5 or 6 scows and tug boats simultaneously.  The car storage yards are in the background.

On the right side about half way up the photo there is a switch siding with a short section of track containing what looks like a small dump or something.  Not sure what that is.

I visited the N&W coal piers some years ago as part of a tour group.  They were a little different then.
