BNSF Railway's Q-WSPNBY1-05A (Willow Springs IL to North Bay CA guaranteed service intermodal) winds through the Tehachapi Mountains at Bealville, California, on November 7, 2009. The quartet of Dash 9-44CWs (5259, 4795, 5154 and 1115) are about to duck into Tunnel 2 as they descend into Caliente and, eventually, Bakersfield before fast running up the Central Valley to the train's destination in the San Francisco Bay Area.
