Second train of the day is a mixed freight headed by UP 4010. I think it is an EMD SD70M, so correct me if I am wrong. If the wind is right, these locomotives can sneak up on you. I keep a good eye out when along the tracks, and spot most trains a ways off. But on rare occasion you won't hear them at all and they'll be passing you before you know it. Still, nothing can beat the thrill of a big freighter sailing by at 70mph!
