Steve - I will second Ed with the Ronkonkoma location looking eastward.
The yard building for train and maintenance crews is just off to the left out of the picture...
What I question is the date 1954 - this looks older remembering the position light station signals that were
at the same location - it all depends when the pictured semaphores were replaced. The passenger cars in
the background look like ping-pong types along with a few freight cars - and no visible locomotives...
