Amtrak train No. 5, the westbound California Zephyr, exits Tunnel 8 and curves around the former location of Tunnel 9 on a 2 percent grade through the tunnel district west of Plainview, Colorado, on the morning of June 8, 2013. Tunnel 9 became so unstable that it was bypassed by a shoo-fly and eventually daylighted, with the grade moved to its original survey as seen here. Fresh and bright colors of springtime have reached the high country of the Rocky Mountains, as the great plains stretch out in the background far below.
