Special passenger service was only offered during World War II on the Air Base branch to transport military personnel to the Santa Maria Army Air Base for training. The Air Base branch was constructed in 1943. Excursions were offered for the first time on the SMVRR in November 2006, continuing into 2007.

The SMV was incorporated on July 14, 1911 as the Santa Maria Valley Railway at Los Angeles, California with A. A. Dougherty listed as President.^[1]

The first 3.26 miles (5.25 km) of track, from the Southern Pacific connection at Guadalupe to Betteravia Junction, was actually built by the SP in August 1899 to get to a sugar mill. The SP leased the track to the SMV years later. From Betteravia the SMV built to Santa Maria and on to Roadamite. The SMV also had branches running from Stowell to Air Base, Suey to Rosemary Farms and Rex to Gates.

By 1925 the railway traffic had steeply declined and the railway went bankrupt. Captain George Allan Hancock , a principal of the Dominion Oil Company, purchased the railroad for $75,000 at a Sheriff's auction. The railroad was then reorganized as the Santa Maria Valley Railroad in 1926. Until 2006, the railroad was owned by Captain G. Allan Hancock's estate.

The original line ran for 23 miles (37 km), from Guadalupe to Roadamite. The track from Gates to Roadamite was abandoned in 1950.

The last run of No. 21, Captain Hancock's favorite steam locomotive, was in February 1962. Captain Hancock took the throttle one last time. Walt Disney was in the cab with Captain Hancock.

Baldwin 21 currently is undergoing restoration in Astoria, Oregon to be returned to excursion service.

The Union Sugar Beet plant closed in 1993, ending the beet train era.

In 1999 the G. Allan Hancock Estate gained full control of the SMV. The assets of the railroad were sold to Coast Belle Rail Corporation in 2006, ending an 81-year ownership by the Hancock family.

Other than No. 21, three other steam locomotives are in existence. Following a successful 38 year restoration, the Baldwin Locomotive Works 1924-built No. 205 was sold to the Albany and Eastern Railroad in Lebanon, Oregon and is used on the Santiam Excursion Trains.^[2] No. 100 is in Nevada, but has not yet entered restoration by the Virginia and Truckee. No. 1000 resides on Static Display in Griffith Park at Travel Town.
