If your view (of the train) is obstructed (blocked with some type of wall or a building or your inside a dome) would the light from a train passing 2 miles away affect your photo?
That is my situation, I live 14 miles east of T or C, nm so the skies are pretty good otherwise. It's desert so the trains that come by are plainly visible and cast pretty vivid shadows on my buildings as they pass by. (from their headlights three very bright ones)
