 Freight service, which consists primarily of moving shipping containers to and from the Port of Oakland, is provided today by Union Pacific Railroad (UP), and to a lesser extent by BNSF Railway (which now shares the tracks of the UP between Richmond and Oakland).Historically, Oakland was served by several railroads.Besides the transcontinental line of the Southern Pacific, there was also the Santa Fe (whose Oakland terminal was actually in Emeryville), the Western Pacific Railroad (who built a pier adjacent to the SP's), and the Sacramento Northern Railroad (eventually absorbed by the Western Pacific, which in turn was absorbed by UP in 1983).
