Significance: This small building was constructed as an electrical substation for the Key System trains that originally ran on the Bay Bridge, from Oakland to the Transbay Terminal in San Francisco. It was a vital component of the Bay Bridge. Although electric trains no longer run on the bridge, this building has retained its original use as an electrical substation and its association with the historic bridge. The building also possesses a high degree of integrity, with alterations limited to replacement of the electrical equipment that it contains. The building is therefore eligible for National Register listing as a contributing component of the Bay Bridge.
