Arrival of the Railroad

From 1891 - 1978
America's Golden Age of Railroads began in the late   nineteenth century. California's first railroad was built in Sacramento in 1856   and the transcontinental line was completed when the "Golden Spike" was driven   in 1869. This led to rail lines being constructed throughout the Bay   Area. 
The San Ramon Branch Line railroad opened in 1891   after much dreaming, lobbying and planning for rail service by local citizens.   They knew train service would allow freight and passengers to be transported   in winter rainy seasons when County roads were impassable. After Danville   Grange No. 85 was organized in 1873, members were involved in several efforts to   bring a railroad to the valley. 
Early in 1890 a young entrepreneur, William Kye,   grandly announced plans for a new transcontinental railroad that would go   through Alamo, Danville and San Ramon. Kye said he was willing to pay for the   right-of-way land and his crew proceeded to survey the valley. 
This activity rekindled the interest of the   Southern Pacific Railroad (which had done an 1887 survey) and meetings with   landowners began in May of 1890. However, the Southern Pacific would not pay   for the right-of-way. More meetings were held. Some landowners were willing to   donate land, other were not. In the meantime Kye disappeared, leaving the field   to SP.

A core committee of farmers, including August Hemme   of Alamo, R. O. Baldwin of Danville, Charles Wood of Sycamore Valley and George   McCamley of San Ramon, was determined that this time a railroad would be built. They and others helped raise $15,000 to purchase the right-of-way from   reluctant owners; the rest was donated. 
Grading of the route began late in 1890; early in   1891 tracks were laid and the Branch Line was completed. The line extended   from San Ramon to Avon (3 miles east of Martinez) for 20 miles where it   connected with the Oakland/Stockton line. The first regular trip took place on   June 7, 1891. In 1909, SP extended the line to Radum (near Pleasanton) where it   connected to the Oakland/Tracy line.
