Southern Pacific Diesel Shed, Tracy

For nearly five decades, the Southern Pacific Railroad utilized two massive roundhouses at its railyard near downtown Tracy. The roundhouses were constructed to service and repair steam locomotives at Tracy, which was a major waypoint on the SP during the first half of the Twentieth Century.

In the mid-1950s, the Southern Pacific began the complete phase-out of steam locomotives, replacing their entire fleet with more reliable diesel-electric locomotives, which required substantially less maintenance.

At the same time, the SP chose to reduce and relocate its facilities in downtown Tracy, moving its storage yard farther east of town – on the far side of the Eleventh Street overpass, spanning the area east nearly to Banta. (The relocated yard opened in 1961.)

With the relocation, down came the roundhouses and up grew a simple “shed” near the SP’s new depot at the foot of Sixth Street near MacArthur, providing just enough space to service one or two diesel locomotives at a time. A refueling dock and sanding station – essential to provide additional traction for heavy trains heading over the Altamont – were also constructed.

The diesel facility remained in use into the 1990s, after which it was shut down. Subsequently, its windows were covered with plywood sheets, its huge doors were sealed shut, and the rails leading up to it were torn out.

Mileposts: Holly Sugar Corp. Refinery, Tracy (MP 73.5)

It’s perhaps the most visible landmark across the flatlands of western San Joaquin County – a cluster of tall, white silos bearing the Holly Sugar brand – which can be seen from miles away, towering above the landscape north of Tracy.

The Holly Sugar refinery in Tracy’s rural outskirts went online in 1917 as the Pacific Sugar Corporation. The plant originally received beets by way of trucks, and later via barges that utilized a man-made waterway known as “Sugar Cut” that diverts from Tom Paine Slough and Old River, north of Tracy.

Union Pacific “Mothball Fleet” In Tracy

A recent downturn in railroad revenues has turned the once-busy Union Pacific Railroad yard in Tracy into a pasture of sorts.

The UP’s yard here, which extends east from the Eleventh Street overpass downtown nearly to the town of Banta, has become the “rest home” for about 85 of the railroad’s locomotives that have been put out to pasture, stored here in hopes of a future rebound in freight shipments via rail.

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.

Alameda & San Joaquin Railroad

(This article is a perpetual work in progress.)

If you’ve taken a load of trash to the dumps here in Tracy, you can’t avoid the solid bump of crossing what appears to be an abandoned set of railroad tracks protected by mute crossbuck warning signs a hundred or so feet down MacArthur Drive south of Linne Road.

The tracks are seldom used but are not entirely abandoned these days. Occasionally — very occasionally — the Union Pacific will spot a couple of freight cars loaded with steel coils there, alongside the Calaveras Materials rock grinders and the Teichert Aggregates entry gate on MacArthur.

“Days Of First Railroad”

When visiting the Tracy Historical Museum, if you only see what is directly in front of you, you may miss something magnificent farther above eye level.

Among those “somethings” is a rare and wonderful mural by the Oakland-born artist Edith Hamlin (1902–1992), whose other works included murals at Coit Tower and Mission High School in San Francisco, and at the Department of the Interior in Washington, D.C.

Shortly after the United States Post Office opened at the corner of 12th and Adam streets here in 1937, Miss Hamlin painted a series of three murals depicting Tracy’s early history.

Eastbound OAMJM At Tracy, 1981

Fresh into our yardmaster’s office today is this big win off of eBay, showing Southern Pacific Railroad SD-9 4426 and partner(s?) leading a string of cars under the old Eleventh Street overpass in 1981, headed out of town toward Banta and Mossdale.

This view can no longer be replicated for several reasons, not the least of which is the tear-down and rebuild of the old overpass.

Southern Pacific Railway Yards, Tracy

The backside of this picture postcard has “Monday, Oct 25, 1948” penciled in script, so we’re guessing that this view of the Southern Pacific Railroad’s yard is from the mid to late 1940s.

The caption under the photo on the postcard reads “Southern Pacific Railway Yards and Shops, Tracy, California.”

If you’re looking at this photograph today, imagine yourself on the roof of the Tracy Transit Center, facing toward the new-fangled overpass that recently opened, taking 11th Street over the Union Pacific tracks.

Jack Godwin, Carbona Station Agent

Jack Godwin served as station agent at the Western Pacific Railroad’s Carbona depot from 1954 until his death in 1974. Ten years after he arrived, wife and children in tow, the WP renamed the stop “Tracy” on their timetables, as well as on the station’s roof-top nameboard.

The Ted Benson photo featured above shows Jack in a classic railroader’s pose, fingers on the telegrapher’s key, carrying on a conversation with his colleagues down the line in well-timed dots and dashes.

The San Joaquin Daylight

Showing here (above) is a portion of the schedule for the San Joaquin Daylight for the segment during which it traversed the so-called “Mococo Line” (from MOuntain COpper COmpany) from Martinez to Tracy and back again, excerpted from the Southern Pacific’s official Timetable #10, issued on May 12, 1968.

Following the SP’s practice of designating “east” and “west” on its timetables based on the location of its Market Street corporate headquarters in San Francisco, the “eastward” San Joaquin Daylight (Train 52, originating in Oakland) is actually heading south to Los Angeles, while the “westward” return trip (Train 51, originating in L.A.) is heading north to Oakland.
