My shot of the weekend, UP 5728 and 7527 along with a leased SD40-2 wind their autorack train out of Tunnel 35 and down the single track grade at Yuba Pass.
UP Dash 8 9556 leading loaded auto racks from the Bay Area to the Heartland. This train is heading up and over Donner Pass, just about to enter Tunnel 35 on the single track.
