The Sutter Street Railway could trace its history back to 10th December 1868 when a horse car line on Pacific Avenue opened. Renamed from the Front Street, Mission and Ocean Railroad to the Sutter Street Railroad in 1872 it was converted to a 5' gauge cable operation in January 1877. A further conversion to electric operation came from 1902 when it was merged into the United Railroads of San Francisco but the Pacific Avenue line remained as a cable car because of the grades involved in this line. This line carried on running until 29th November 1929 when it was closed but a couple of vehicles were retained and ownership of these passed to the Municipal Railway of San Francisco when it purchased the assets of the Market Street Railway (who had been the final owner of the cable car line) in 1944. This view shows no. 46, built in the 1880s and a four wheel open grip car with back to back seating, in the Cable Car Museum during 1998.
