The wind was the thing. A freight train moves a lot of air. Each type of car doing it a little differently. The result was a swirling wind that alternately pushes away from a train and then towards it.
This was an unexpected shoot. I had already taken what I had gone to the track for and was heading towards the stairs when I heard the horn. The engine was through before I could get the camera out. But the cars and noise and wind were mesmerizing.
Here are two minutes of a freight train that had somewhere else to be.
I have no idea how to use this clip as a greeting card. Happy to take caption suggestions at http://www.onceuponagreeting.com
