Track one was removed in 1993 by SP but up until that time was still in daily use, although the "scenic route" from shed 47 to Norden rarely saw much traffic in later years. You will occasionally hear the single track section from switch 9 to shed 10 referenced today as the "Moyers Main" as it was Ed Moyers who came along and ripped up track on Donner and sent it down to the Sunset Route for expansion there. If he had had his way, Sparks to Oakland would have been a single track line with sporadic sidings...thankfully, wiser minds prevailed on that one.
