The first McCloud trains were log trains bound for the mill at Upton, then McCloud. Passenger trains were first created in 1902 and went from Upton/Sission to Bartle, the current end of the line. The lumber company would lease the McCloud locomotives and base them around the mills. When the Lookout Line was built, besides the log and passenger trains, two trains would operate to each interchange daily. This schedule remained the same until 1955, when the Burney Branch was built. By this time, diesels were arriving and two were assigned on the Branch; one to bring a train from McCloud to Burney, and another to exchange loads/empties at Berry.
