General Engineering & Dry Dock Company was a shipbuilding and ship repair company in Alameda, California that was active from the 1920s through the 1940s. The company built ships for the Southern Pacific Railroad and the United States Coast Guard in the late 1920s and early 1930s and took part in the World War II shipbuilding boom, making diesel-propelled steel hulled auxiliaries for the United States Navy, primarily oceangoing minesweepers.

The Steel Electric-class ferries are a class of auto/passenger ferries that became part of the Washington State Ferry System when Puget Sound Navigation Company was acquired in 1951. They were built in San Francisco Bay for service on Southern Pacific and Northwestern Pacific Railroad routes across the bay.
