Mileposts: Bethany (MP 75.7)

The village of Bethany could, once upon a time, be found along the Southern Pacific Railroad’s Martinez-to-Tracy extension, just a few miles outside the latter city’s limits.

These days, few signs remain of Bethany: an old farm road that ends near the tracks is perhaps the most significant remnant. (A reservoir in the nearby Livermore Hills is named for the town, but is several miles distant.)

The Central Pacific Railroad built a depot at Bethany around 1878 along the extension, which was constructed as the San Pablo & Tulare Railroad; in the early Twentieth Century, this section of tracks appeared on USGS maps – including the one below from 1914 – as the Southern Pacific’s “San Francisco and New Orleans Line.”

Today, it is known to railheads as the “Mococo Line.” It was the construction of this extension that led directly to the birth of Tracy at the end of the 1870s.

Associated Oil Tank Farm – Tracy, California

For decades, oil from Kern County was transported by rail in tank cars (appropriately dubbed “oil cans”) to this Associated Oil storage facility in Tracy, which served as a way station as the oil traveled to Port Costa.

In the aerial photo from 1926 (shown above and below), the tracks heading to the right are part of the Mococo Line, which is now a seldom-used single track that extends up through Byron and Brentwood into Antioch and Pittsburg.

In the distance, just right of center in the photograph is an oil reservoir (also known back then as the “Gravel Pit”), which was located approximately where Alden Park is today.

The Mococo Line was fundamental to the creation of the city of Tracy, which was founded in 1878 when the nearly fifty-mile-long line was opened between Martinez and here.

Originally constructed as the San Pablo & Tulare Railroad, it was built as an extension — a shortcut, as it were — connecting the Central Pacific’s established northern line near San Pablo Bay and its line through the San Joaquin Valley via Stockton and Lathrop over the Eastbay Hills to Oakland. (The SP&T was consolidated into the Southern Pacific Railroad, the successor to the Central Pacific, in 1888.)

All that currently remains of this facility today is a group of hillocks at the corner of Tracy Blvd. and Beechnut Avenue, across from the city’s corporation yard.

Contaminated soil in the area led to a landmark court case, Cose v. Getty Oil Co., over who was responsible for waste from the tanks that had seeped into the soil surrounding the “Gravel Pit.”
