One of the ships docked at the Hyde Street Pier is the former Northwestern Pacific ferry boat Eureka.
In the era before bridges, (the Bay and Golden Gate), the only way to get from San Francisco to Marin or Oakland by rail, was by rail ferry.
The passenger cars would be boarded on the ferry and then, well, ferried, across the Golden Gate to Sausalito or Tiburon where they would be unloaded and continue north on the rails of Northwestern Pacific.

The boat was built in 1890 in Tiburon by San Francisco and North Pacific Railroad Company and was originally named the Ukiah, which was as far north as the line reached. The Eureka is a double-ended, wooden hulled ferry-boat that was originally built to hold train cars. Two standard-gauge tracks where built into the main deck.
This 277 foot, 2,564 tonnage boat is the largest wooden-hulled boat afloat in the world.

The Ukiah was initially in service to ferry people from San Francisco to Tiburon during the day and then carry freight cars during the night. In 1907 the Northwestern Pacific Railroad took ownership of the Ukiah and it was routed to the Marin port of Sausalito.
During World War I, the ferry was rebuilt and the refurbished ferry was renamed the Eureka, in honor to the northernmost station on the Northwestern Pacific Railroad.

The ferry was later used to ferry automobiles on her main deck and had a capacity of 2, 300 passengers and 120 cars. At this time, the Eureka was the largest and fastest double-ended passenger ferry in existence and because of this, the Eureka was called up for the busiest commuters times from Sausalito to San Francisco. Hyde Street pier was the primary auto terminal to connect San Francisco to points north and east.
When the Golden Gate Bridge was completed in 1937, ferry service passengers dried up and Northwestern Pacific abandoned all ferry service in 1941.
The Eureka found a new life in the 1950s with a new owner, the mighty Southern Pacific. The Eureka now linked passengers on SP’s overland service from Oakland to San Francisco.
