The photo was taken from the pedestrian bridge of the railway station. Some passenger train was preparing to leave for the depot at night. You can try to see a person who is inspecting the train with a flashlight (but only the trace of the flashlight is visible)
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
