Swanton Pacific Railroad


The Swanton Pacific Historical Railroad Society is dedicated to those who:
  • Are nuts about trains
  • Have a love for history
  • Like to be working on a fun project outdoors
  • Want live steam maintenance or operating experience
  • Have or want machine shop, welding, construction or foundry experience
The 1/3 scale railroad is located on the beautiful 3200-acre Swanton Pacific Ranch near Davenport in Santa Cruz County.  A dedicated group of volunteers maintain and operate the railroad on behalf of the Cal Poly College of Agriculture, Food and Environmental Sciences.  The Swanton Pacific Railroad serves as an operational memorial to Al Smith who acquired and relocated the trains to the Swanton Pacific Ranch. The rolling stock consists of three one-third scale Pacific-type steam locomotives that were built for the 1915 Panama-Pacific International Exposition, a diesel switcher locomotive and a variety of passenger and maintenance of way railcars.

2018 Events

  • Al Smith Day - Canceled

    • The 2018 Al Smith Day has been canceled.  We continue to work to restore track that was damaged last winter.  Given the location of the damaged track we are not able to offer train rides.  We are optimistic that we will have the wash out repaired this summer. 
  • Cal Poly Day - 

    • The Cal Poly Day for 2018 is currently in the planning stages.  We are working with the Swanton Pacific Ranch and the College of Agriculture, Food and Environmental Sciences to plan an enhanced Cal Poly Day event for late September.  Please check back here to get updates.   


Informal Visits

  • If you want to visit the Swanton Pacific Railroad to learn more about what we do, please feel free to visit us on any of our regular volunteer work weekends. The volunteers work weekends start on the second Saturday of each month. The hours are informal but work normally starts around 9 and wraps up around 5 each day.  The volunteers will be happy to show you around and tell you about the history of the railroad and explain the work they do to keep the trains rolling.
