Locomotives gather on the fuel tracks at Union Pacific’s former Rio Grande North Yard at Denver, Colorado, on December 22, 2012. The yard tower is visible above the locomotive on the right.
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!)
