Niles Canyon Railway

Highlight β€’ Historical Site

The history of trains in Niles Canyon dates back to the building of the original transcontinental railroad. The first Western Pacific Railroad Company (formed in 1862) started construction in San Jose towards Sacramento. It built twenty miles of track that reached into Alameda Creek canyon in 1866. Its first passenger excursion entered the canyon on October 2 of that year. Construction was halted shortly thereafter, however, because of disagreements between the railroad’s contractors and its financiers. In September, 1869, four months after the famous golden spike ceremony at Promontory Summit, Utah, the Central Pacific Railroad completed the transcontinental rail link between Sacramento and the San Francisco Bay, finishing the track through the canyon. The CP had acquired the Western Pacific and other local railroads and built track to connect them at a waterfront terminal at Alameda Point. Very few rebuilding programs by the railroad left the Niles Canyon line with much of its original cut stone bridge abutments, culverts and retaining walls from the original Western Pacific’s right of way (circa 1865). These unique constructions can still be seen today.
Steam locomotives pulled trains through Niles Canyon for eighty years before diesels took over in the 1950s. In 1984, after twelve decades of railroading in the canyon, the Southern Pacific ceased operating trains on the right-of-way, pulled up the tracks, and deeded the land to Alameda County.
The Pacific Locomotive Association entered into an agreement with the county and began rebuilding the rail line in 1987. Association volunteers worked for over a year on the first part of the track reconstruction between Sunol and Brightside. On May 21, 1988, almost 122 years after the first Western Pacific excursion, the Pacific Locomotive Association brought railroad passenger operations back to life in Niles Canyon. Presently, Niles Canyon Railway provides train rides to the public year-round between Sunol, California and Niles in Fremont, California. ncry.org

Entry point to the Hayward Shoreline trail. You'll have to travel through some industrial areas to reach this point, and the trail is gravel. Not overly populated, but there is some road noise from the San Mateo bridge.

Long gravel stretch was no issue for my hybrid commuter on a dry day. Nice and quiet, it's a lightly populated trail.
