Late afternoon in Bio-Bio river mouth and passenger train (commuter service) from Lomas Coloradas crossing the long 2 Km (1,24 miles) railway bridge connection Concepción and San Pedro de la Paz, with destination Concepción city.
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!)
