After meeting the eastbound California Zephyr 6 train at a siding in east Roggen, Colorado, the California Zephyr 5 train starts running again westbound on the Brush Sub towards Denver.
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!)
