In 1927 the Western Pacific Railroad completed a branch to a landing with access to the Sacramento Delta agricultural region in Terminous. The railroad constructed a "company town" for transshipment of produce from farms on the many islands of the Delta.  Goods arrived by boat and were loaded onto trains for shipment.

The branch, typical of the state of Western Pacific (affectionately known to many as "The Wobbly") was a second class railroad. It hosted for many years and late into the 1940's one of the Western Pacific's oldest locomotives, a diminutive 2-8-0 built in the 1880's. All except a short stub was abandoned in the 1960's. Today Terminous hosts a large marina and campground. Many of the original railroad buildings survive, particularly the waterfront warehouses.Their former railroad service is distinctly apprent by their large freight doors and docks. beyond this, remnants of the railroad are scarce, however.  Terminous lies on State Highway 12, about 6 miles west of I-5.
