On May 5, 1990, I spent the morning following Southern Pacific’s timetable westward MERV-M (Medford, Oregon to Roseville-Manifest) on the sinuous and steeply graded Siskiyou Line. This was led by SP SD45E 7504, which retained its 3,600 hp 20-645E3 diesel engine.

I made this photo at Ager (railroad timetable west of Hornbrook, California) on the run toward Black Butte. At the time SP was operating 7,500 ton trains on this amazing stretch of railroad.

Exposed on Kodachrome 25 using a Leica M2 with 50mm Summicron about 9:25am.

I made dozens of photos on that beautiful May morning. Most remain unlabled, although I have all my notes from that day. I was delighted to have an SP unit with its oscillating lights in the lead. Since at that time SP was actively removing the oscillating lights from its locomotives.
