In 1864, the Petaluma and Haystack Railroad connected the city of Petaluma to a [[ferries of San Francisco Bay|ferry]] landing at the head of navigation on the Petaluma River.

In 1870, the [[San Francisco and North Pacific Railroad]] (SF&NP) connected the City of Santa Rosa to ferry connections at Donahue landing on the Petaluma River. Rail service was extended north to Healdsburg in 1871 and Cloverdale in 1872. In 1884 the railroad was extended south to an alternate ferry connection in [[Tiburon, California|Tiburon]]. This rail line serves as the primary route of Sonoma–Marin Area Rail Transit.<ref>{{cite web |url=http://www.sonomamarintrain.org/about-smart |title=About SMART |website=sonomamarintrain.org |date=September 26, 2016 |access-date=December 31, 2017 }}</ref>

The [[narrow-gauge railway|3-foot-gauge]] [[North Pacific Coast Railroad]] extended northward in 1876 from a ferry connection at Sausalito through Valley Ford, Freestone, and Occidental to Monte Rio on the lower Russian River. Service was extended to Duncans Mills in 1877 and Cazadero in 1885. The [[standard gauge]] Fulton and Guerneville Railroad left the SF&NP at Fulton to reach [[Korbel Champagne Cellars|Korbel]] in 1876 and Guerneville in 1877. Standard-gauge rails were extended down-river to [[Duncans Mills, California|Duncan Mills]] in 1909 after the [[Northwestern Pacific Railroad]] merger, and narrow-gauge service was discontinued in 1930. The standard-gauge route became River Road after tracks were removed in 1935.<ref>{{cite book |last1=Codoni |first1=Fred |last2=Trimble |first2=Paul Castelhun |title =Northwestern Pacific Railroad |publisher =Arcadia Publishing |date =2006 |page =65 |isbn =0738531219}}</ref>

The unique Sonoma Valley Prismoidal Railway linked the city of Sonoma to bay ferries in 1876 and was replaced in 1879 by the {{convert|3|ft|m|adj=on}}-gauge Sonoma Valley Railroad to a ferry landing near the mouth of the Petaluma River. Service was extended from Sonoma to [[Glen Ellen, California|Glen Ellen]] in 1882. The southern end of the line was extended westward in 1888 to a connection with the SF&NP at [[Ignacio, California|Ignacio]]. This line was converted to standard-gauge in 1890 and remains (in 2018) as Sonoma County's connection to the national rail system at [[Schellville, California|Schellville]].

[[Southern Pacific Transportation Company|Southern Pacific]] subsidiary [[Santa Rosa and Carquinez Railroad]] extended eastward in 1888 to link Santa Rosa with the national rail system. The portion between Sonoma and Santa Rosa was dismantled in the 1940s after interchange shifted to the former Sonoma Valley line.<ref>{{cite web |url=https://localwiki.org/sonoma-valley/Railroads |title=Sonoma Valley Railroads |website=Sonoma Valley |publisher=LocalWiki |access-date=April 1, 2018 }}</ref>

A SF&NP branch line from Santa Rosa brought rail service to Sebastopol in 1890. The [[Petaluma and Santa Rosa Railroad]] extended [[interurban]] service north from a ferry connection in Petaluma to reach Sebastopol in 1904, Santa Rosa in 1905, and Forestville in 1906. Portions of this line were converted to the [[Joe Rodota Trail]] after tracks were removed in the 1980s.<ref>{{cite web|url=http://www.sonoma-county.org/parks/pk_westc.htm|title=West County and Joe Rodota Trails|website=Sonoma-county.org|access-date=April 1, 2018}}</ref>
