J.R. Davis Yard is a railway hump yard in Roseville, California owned by the Union Pacific Railroad. It is located along the confluence of three of the railroad's lines: the Martinez Subdivision heading southwest to the Sacramento Valley, the Roseville Subdivision which runs over the Sierra Nevada Mountains into Nevada, and the Valley Subdivision which heads north to Lincoln and Marysville. It takes its name from the last president of the Southern Pacific Transportation Company, Jerry R. Davis.[1]
The yard covers 780 acres (320 ha),[2] with a bypass for passenger trains on the north side.[1] It is capable of handling 2,000 cars per day.[3] It is also used to store Union Pacific's snow removal fleet which work the Sierra Nevada.[4]
