The Tidewater Southern Railway was a short line railroad in Central California in the United States. For most of its history, it was a subsidiary of the Western Pacific Railroad. It was originally built as an interurban system, connecting to the Central California Traction Company, Western Pacific Railroad, Southern Pacific Railroad and Atchison, Topeka and Santa Fe Railway in Stockton, California. Its mainline went southeast from Stockton to Escalon, California and thence to Modesto, California before splitting into two branches ending at the towns of Turlock and Hilmar. Until the mid-1930s, there were plans to extend the line to Fresno and even toward the Los Angeles area. Today, much of the line is still operated by the Union Pacific Railroad. Of all the former interurban railroads in California, the former Tidewater Southern retains the highest percentage of still operating trackage.

The railway was incorporated in 1910; construction from Stockton began in 1911 and service to Modesto began in 1912 with steam locomotive-hauled passenger service. Electrification, using a 1200 VDC overhead system, [1] was completed in 1913, and regular electric car service began on a 2-hour schedule. In addition to passenger service, the railway operated extensive freight service in the area.

In 1916, the railway was extended to Turlock, California, and in 1917 to Hilmar, California. The lines to Turlock and Hilmar split at a junction known as Hatch, California. This portion was never electrified and never operated passenger service, being purely for freight. A freight-only branch to Manteca, California was constructed in 1918. While many references list this branch as being unelectrified, evidence from the TS mechanical department and the Western Pacific's accounting files show that the line did in fact have overhead wire and was operating with electric locomotives.

Most of the stock of the railway was purchased by the Western Pacific Railroad in 1917, [2] but the WP began influencing TS actions as early as 1913. The railroad was operated as a subsidiary thereafter.

Passenger service was abandoned in 1932 [2] and the railway operated solely as a freight line, with the exception of offering passenger carriage in the line's cabooses. This situation lasted until the 1960s, with the parent company reportedly having forgotten to formally abandon the passenger tariff. The electrification was dismantled after this point except in Modesto, where a city ordinance prohibited the operation of steam locomotives. The railway therefore retained 2.1 miles (3.4 km) of electrification within Modesto, and the railway's two steeplecab electric locomotives. Outside Modesto, all freight traffic was now steam hauled. Additional steam locomotives were borrowed from the Western Pacific when needed. In 1940, a former Sierra Railroad steam engine was acquired.

Busy traffic during World War II increased the Tidewater Southern's traffic hugely, and locomotives were borrowed from other roads to handle it, including two Sacramento Northern Railway box motors, several steam locomotives and a number of WP diesel locomotives, the first on the system.

After the war, the acquisition of more diesel locomotives led to the rapid retirement of the railway's electric locomotives and one of the steam locomotives, although steam traction was retained until several bridges were upgraded in the late 1950s to bear the weight of diesel locomotives. TS steamer 132 was the last in operation, probably performing the last revenue steam work on the Western Pacific system in October 1953. Starting in the mid-1950s, the line also added a small fleet of modern freight cars, some of which survived until the early 1980s.

From the late 1960s, the system's independence began to decline as it became increasingly operated by Western Pacific locomotives and crews, until it became a "paper railroad", nominally a separate corporation but invisibly so in actual operation. Its traffic, however, continued to expand. The construction of several grain silos near Turlock, used to supply animal feed, eventually required long unit trains to bring in the volume of Midwestern grain required to fill them. By the late 1970s, these trains were the main traffic on the line and led to much anger from the city of Modesto, where the mainline occupied the middle of Ninth Street, the major north-south roadway. The last locomotives and cabooses lettered for the TS were retired in late 1976.

While the WP purchased most of the road's stock in 1917, it did not acquire complete control until some time in the 1960s. A small amount of the common stock (around 4%) was owned by private individuals and the road sent letters to them annually reporting on the company's state and finances. The end for the Tidewater Southern as a company came in 1983 when the Union Pacific absorbed the railway's parent Western Pacific Railroad. Final merger into the UP occurred in 1986, when the TS corporate structure was abolished.

Since 1983, the remaining portions of the Tidewater Southern have been the Tidewater Subdivision of the Union Pacific. In 2001, the line on Modesto's Ninth Street was abandoned, severing the railroad in the middle. The Turlock-bound grain trains now bypass the north end of the railroad and enter former TS rails just south of Modesto. The north end is still served by one train 3-4 times a week. The branch to Manteca was abandoned in the early 1990s.


The Tidewater Southern only ever owned three interurban electric passenger cars; all were built by the Jewett Car Company in 1912 and bought new. This roster was unusual in that all were combine cars, each having a freight section. The Tidewater was one of the few interurbans to never roster a "pure" electric passenger car. When extra capacity was needed, passenger trailers were borrowed from the Central California Traction Company.

It also owned two steeplecab electric freight locomotives: [1] one was a stock General Electric model, while the other was built by the Central California Traction Company from an old flatcar.

Old newspaper reports and company records indicate that Jewett also built an express motor, but no photos of it have come to light publicly.

The road rostered three steam locomotives, with one only being used in the earliest days of the line.

Small General Electric diesel switchers replaced the steam and electric locomotives. These were later displaced by larger locomotive made by the American Locomotive Company. Western Pacific locomotives took over all operations by the mid-1970s.

When traffic was heavy, steam engines and later diesels were borrowed from the Western Pacific Railroad. Electric freight motors were also borrowed from time to time from sister roads Sacramento Northern Railroad and Central California Traction until the electrification was abandoned. The TS never owned or operated a maintenance facility for its locomotives and cars. All work on the interurban cars and electric locomotives was performed by the CCT at their shops in Stockton. Repairs on TS steam and diesel locomotives, as well as freight cars and cabooses, were performed by the Western Pacific.

In the 1950s, the railroad built up a sizable fleet of freight cars, mostly insulated boxcars. One series of 25 cars wore a unique herald of a "Cornucopia" and bore the legend "Serving California's Heartland". This herald was one of the most colorful and complex ever used by an American railroad and is still remembered today. One of these cars is preserved at the Western Pacific Railroad Museum and its heralds has been restored, although they have been skillfully hand-painted, rather than being decals as in the original paint scheme.

Preservation and survivors

TS interurban car 200 is stored indoors, unrestored, at the Western Railway Museum. Two of the famous Cornucopia freight cars are preserved at the Western Pacific Railroad Museum at Portola, along with a former Western Pacific bunk car. This car, TS 0565-H, was used as the depot in Escalon for many years after a fire destroyed the original station. Caboose 305 is preserved in Modesto and will eventually be placed on the former right of way in the northern section of the city, which has now been turned into a linear park.

Several other pieces of equipment also survive:

The only remaining depot building is the freight depot in Turlock. The Hotel Stockton, which had interurban offices and waiting area on its first floor, also survives.

Interurban Type of electric railway which runs within and between cities or towns

The Interurban is a type of electric railway, with streetcar-like electric self-propelled rail cars which run within and between cities or towns. They were very prevalent in North America between 1900 and 1925 and were used primarily for passenger travel between cities and their surrounding suburban and rural communities. The concept spread to countries such as Japan, the Netherlands, Switzerland, Belgium and Poland. Interurban as a term encompassed the companies, their infrastructure, their cars that ran on the rails, and their service. In the United States, the early 1900s interurban was a valuable economic institution. Most roads between towns and many town streets were unpaved. Transportation and haulage was by horse-drawn carriages and carts. The interurban provided reliable transportation, particularly in winter weather, between the town and countryside. In 1915, 15,500 miles (24,900 km) of interurban railways were operating in the United States and, for a few years, interurban railways, including the numerous manufacturers of cars and equipment, were the fifth-largest industry in the country. By 1930, most interurbans in North America were gone with a few surviving into the 1950s.

The railroad was unique in that it had operated for nearly 50 years exclusively with GE 70-ton switchers built between 1947 and 1955; however, a former Southern Pacific EMD SW1500 switcher was added to the roster as of late). The MET operates on 5 miles (8 km) of mainline track, as well as an additional 48.7 miles (78.4 km) of yard and industry track, providing switching services in the Beard Industrial Park. The MET interchanges with the Union Pacific at Modesto and with the BNSF Railway Stockton Subdivision at Empire.

Railroad electrification in the United States began at the turn of the 20th century and comprised many different systems in many different geographical areas, few of which were connected. Despite this situation, these systems shared a small number of common reasons for electrification.
