During a cold autumn rain in Denver, Colorado, on the evening of November 7, 2017, an A Line RTD commuter train from the airport arrives at Denver Union Station.
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!)
