During the annual sugar beet campaigns, Southern Pacific and California Northern interchanged trains to/from the Klamath Basin at Tehama, California. On this day, the CFNR crew has cut off their train of empties and parked their power in the clear on the east leg of the Tehama wye. The SP crew has uncoupled from their train of loads, and they are moving to couple onto the loads. Once SP clears, the CFNR units will get on the loaded train so they can deliver it to the sugar refinery at Hamilton City.
