Cold Day in Indiana

We were coming back from a road trip to see friends in St. Louis when we stopped for the night in Corydon, Indiana. The next morning dawned cool and clear and in the crisp winter air I swore I heard the sound of a deisel horn. We followed the tracks alongside Indiana Rte. 135 and there to my right was an Alco pulling a string modern tank cars. I got in front of the train as it crossed 135 moving off to the left and setting itself up for a nice broadside shot on a grade crossing. Nice light, cold air... click, click, click.
