This one caught me by suprise. I had passed a south bound CSX about 10 miles up the road. I knew this crossing was here and thought it would give me some good pictures. To my suprise it was a north bound CSX. This is why the pictures are not crisp and sharp. I was not ready for it to be coming from the South. The overpass is in a hollow so the horn echos from end to end making it almost impossible to determine the path of the train.
