Union Pacific #844 crosses over Track 1 at Rocklin as it begin climbing Donner Pass. The 4-8-4 is pulling the 150th Special east over the ex-Southern Pacific Overland Route with the destination of Cheyenne. Just a week previous, this train had passed under this bridge (on Track 1) on its way into Sacramento for the UP's 150th Anniversary celebration at the CSRM.
