On my way out of one location this Amtrak train cought me off guard. I quickly set up my Manfroto tripod, found a near by tree and shined my Stinger flashlight on it to help get my auto focus locked in. Once my focus was locked in, I switch to manual focus. Then prayed for the best. Mind you this all happen very fast. As the train speeded by I shined my Stinger flashlight onto the silver siding of the train to help me capture more of the train features itself and not just the light trails.
