The train is slowly dropping down the hill into Ash Fork.
Jack is still riding the top of a reefer as it pulls into the westbound siding and is looking back toward Bill Williams Mountain. The little town of Ash Fork is off to the right. I think I see about seven steam engines on the other side of the yard at Ash Fork. These were helper engines that would work both ways out of Ash fork to help heavy westbound trains up to Crookton, and almost all eastbound trains up 1,600 feet to Supai, just west of Williams. You can see the elevation drop as Williams is at the base (on the left) of Bill Williams Mountain. At the east end of the yard is an interlocking tower. ATSF installed a mini CTC interlocking in the station at Ash Fork in 1946. It added six power switches at the west end, three at the east end, changed nine semaphore signals to color light and added 14 color light signals. This must have been quite an operation during the steam era. Sad that there is so little of the railroad left there today.
