The train did a photo run by between Harriman and Dale Junction. This gave Steve time to get to Hermosa siding. The Hermosa Tunnels are just around that curve to the left. The engineer is letting the train drift down the hill. With a light throttle, the smoke blows back over and into the cab. Going through Hermosa the engineer will set the train brakes to control the speed of the train as it rolls down the 1.6 percent grade to Red Buttes.
