The Tennessee Valley Railroad Museum hosted Railfest to celebrate their 50th anniversary in 2011, including a night photo session with SOU 2-8-0 #630, seen here at the East Chattanooga, TN turntable 9/2/11.
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!)
