Alameda-class ferry Alameda was the first of three large-capacity ferries intended to transport passengers across San Francisco Bay. Southern Pacific Transportation Company and predecessor railroads had been operating ferries between San Francisco and Oakland, California since 1862. By the early 20th century, service had stabilized on three routes to the San Francisco Ferry Building from Oakland Pier, Alameda, and the San Antonio Creek estuary. Each route required two ferries shuttling back and forth to meet the departure schedule, with a third ferry in reserve when one boat needed maintenance or repair. Southern Pacific's engineering department designed "Alameda" for the heavily traveled Oakland Pier route as passenger counts rose during the period of prosperity preceding World War I. "Alameda" used side wheels for propulsion; but, instead of being powered by a single walking beam engine, wheels were powered independently by two engines for greater maneuverability. The twin stacks were distinctive among 20th century San Francisco Bay ferries.
