State Belt Railroad.

T he State Belt, while not fully a narrow gauge, operated an expansive dual gauge trackage system along the waterfront in San Francisco serving the North Pacific Coast, South Pacific Coast and the Central Pacific. While no proof is known at this time that the State Belt operation lead to interchange traffic between the NPC and SPC, Sanborne maps show us that it was possible.
