Union Pacific’s Denver to Phippsburg freight rumbles through Rocky, Colorado, on the afternoon of October 23, 2011. Three levels of track can be seen here, and the freight will negotiate them all within several minutes. The train is headed for Little 10 curve which will swing it to the middle track. The train will then head east and encircle Big 10 Curve and then be on the closest track, approaching the east switch of the siding at Clay, ready to continue the long climb up the front range of the Rocky Mountains to the Moffat Tunnel on this scenic former Rio Grande route.
