Rob Talbot - Railroad 
I see unfinished rail pieces on both ways but still do not know why you chose to exhibit this image.

Pini - Good point.

But I think the question lies far deeper. 

"Why did I choose to capture this image in the first place?"

That's the real zinger of a question.
I did have the camera in my hand on the day AND the light was good.
I was out for a walk which required crossing the line ... and I did take 3 version of the shot.
But to explain what it was about the scene that made me take it - I seldom can answer.
