I've always found trains fascinating. I took this picture southeast of Austin, TX as I was driving aimlessly looking for cloud formations over the landscape. The clouds weren't cooperating but then I heard a loud blaring train horn and noticed a train approaching from the distance. There was no crossing arm for the train and as you can see in the picture there's only a yield sign. As a result, the train was only moving at most 10 mph. This also allowed me to leave the shutter open a tad longer so I could get a better depth of field. He even waved at me as he went past me.
