Jupiter (locomotive)

Jupiter (locomotive) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jupiter (locomotive) rather than just read about it. In short: The Jupiter (officially known as Central Pacific Railroad #60) is a 4-4-0 "American" type steam locomotive owned by the Central Pacific Railroad. It made history when it joined the Union Pacific 119 at Promontory Summit, Utah, during the golden spike ceremony commemorating the completion of the first transcontinental railroad in 1869.

Reference excerpt

The Jupiter (officially known as Central Pacific Railroad #60) is a 4-4-0 "American" type steam locomotive owned by the Central Pacific Railroad. It made history when it joined the Union Pacific 119 at Promontory Summit, Utah, during the golden spike ceremony commemorating the completion of the first transcontinental railroad in 1869. The Jupiter was built in September 1868 by the Schenectady Locomotive Works of New York, along with three other engines of identical specifications, numbered 61, 62, and 63 named the Storm, Whirlwind, and Leviathan, respectively. These were then dismantled and sailed to San Francisco, California, loaded onto a river barge, and sent to the Central Pacific headquarters in Sacramento. After reassembly the Jupiter was commissioned into service on March 20, 1869, with the other three entering service within the following month.

History

The Jupiter was assigned to the railroad's Salt Lake Division, the third and eastern most segment of the road traveling east from Sacramento, operating in passenger and general goods services as well as construction trains from Toano, Nevada to Promontory Summit, and later Ogden, Utah. When Leland Stanford's train had arrived in Toano, en route to Promontory, its engine was removed from the train and readied for another westbound train, while the Jupiter was to carry Stanford's train on the final leg of its journey to the Golden Spike Ceremony.

Post-ceremony career After the ceremony, Jupiter continued in service for the Central Pacific. In the 1870s, the railroad decided to end their practice of naming their engines, and thus, the Jupiter name was dropped and the engine was simply known as C.P. #60. The locomotive also received many upgrades, including a new boiler, cowcatcher, domes, and smokestack. In 1891, the Southern Pacific, which acquired the Central Pacific in 1885, began renumbering its locomotives, and C.P. #60 became S.P. #1195. In 1893 it was converted to burn coal, and later that year was sold to the Gila Valley, Globe and Northern Railway and designated GVG&N #1. In 1909, the railway, which had been acquired by the Southern Pacific in 1901, sold the engine for scrap.

Reproductions

The Southern Pacific, by 1901, had been placed under the control of the Union Pacific, the management of which remained largely indifferent towards both the Jupiter and the railroad's own no. 119, acknowledging neither's historical significance until well after being scrapped. For events such as the 1939 New York World's Fair and the Chicago Railroad Fair, the Virginia and Truckee Railroad's cosmetically altered Genoa locomotive stood in for the Jupiter in reenactments of the Golden Spike ceremony. In 1924 John Ford made the movie The Iron Horse, which showed a depiction of the ceremony with a title card that reads, "The wedding of the rails -- celebrated with joyous exultation in the uniting of East and West. The afternoon of May 10, 1869. Note: The locomotives shown in the scene are the original Jupiter and [sic] #116." The 1939 film Union Pacific also featured a recreation of the ceremony, in which the Jupiter was portrayed by Virginia and Truckee Railroad's Inyo. In 1969, in observation of the centennial of the Golden Spike, the Genoa again portrayed the Jupiter, posing on a section of restored trackage at the Golden Spike National Historic Park with the Virginia and Truckee's Reno portraying the Union Pacific no. 119. The same year, the Union Pacific operated a special exhibition train, consisting of the Virginia and Truckee's Inyo and Dayton as proxies, along with vintage railroad construction equipment, all displayed on flatcars, which toured various parts of the Union Pacific network through the year. In 1970, the Reno was sold to Old Tucson Studios, while the Genoa was returned to the state of California, with the Inyo and Dayton replacing them as displays at Promontory. In 1974, the National Park Service had approached O'Connor Engineering Laboratories of Costa Mesa, California, to construct exact, full-size replicas of the Jupiter and Union Pacific 119. As was the case with the engines themselves, no drawings or plans of the engines survived, necessitating entirely new drawings to be produced based mostly on photos of the engines as well as research done on similar engines built around the same time. That same year, the existing engines portraying the Jupiter and 119 (the Inyo and Dayton, respectively), had been sold to the state of Nevada, though they remained displayed at the Golden Spike NHP until the construction of the new replicas was complete. Noted railroad historian and steam engine owner Gerald M. Best served as engineering consultant to the Park Service for the project. Former Disney animator Ward Kimball was given the task of painting the replicas. The Jupiter was given a bright red paint scheme with gold leafing, typical of locomotives built in the 1870s. The replicas were completed in 1979, and began operations on May 10 of that year, 110 years after the original Golden Spike ceremony, and continue to make demonstration runs. The replicas originally burned oil, with the wood in the Jupiter's tender being purely aesthetic. In 1991, the Jupiter and 119 replicas were converted to wood and coal burning engines, respectively. In the early 1990s, a vague description of the Jupiter's livery had been found in a recently uncovered March 1869 issue of The Sacramento Bee, in which the engine was said to be blue, crimson, and gold. The engine was repainted into its current livery based on this finding along with further research on liveries of similar engines of the time. The repainted engine debuted on May 10, 1994, coinciding with the 125th anniversary of the Golden Spike ceremony. Additional research has pointed out the managers of the Schenectady locomotive works at the time the original locomotive was built were Scottish, and as such likely would have painted the Jupiter in a shade of blue reminiscent of the Caledonian Railway livery, substantially darker than the shade currently worn by the replica locomotive.

Worked examples

Example 1 — a first encounter with Jupiter (locomotive)

Start with the simplest possible case. Write down what Jupiter (locomotive) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Jupiter (locomotive) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Jupiter (locomotive) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Jupiter (locomotive)

In research
Jupiter (locomotive) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Jupiter (locomotive) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Jupiter (locomotive) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 4-4-0 locomotives, First transcontinental railroad, Individual locomotives of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Jupiter (locomotive) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
