Golden spike

Golden spike is a astronomy 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 Golden spike rather than just read about it. In short: The golden spike (also known as the last spike) is the ceremonial 17.6-karat gold spike driven to mark the completion of the first transcontinental railroad across the United States. It was driven by Leland Stanford to connect the Central Pacific Railroad from Sacramento and the Union Pacific Railroad from Omaha on May 10, 1869, at Promontory Summit, Utah Territory.

Key takeaways

  • Golden spike belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Golden spike to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Golden spike from memory before moving on to harder problems.

Reference excerpt

The golden spike (also known as the last spike) is the ceremonial 17.6-karat gold spike driven to mark the completion of the first transcontinental railroad across the United States. It was driven by Leland Stanford to connect the Central Pacific Railroad from Sacramento and the Union Pacific Railroad from Omaha on May 10, 1869, at Promontory Summit, Utah Territory. The spike is now displayed in the Cantor Arts Center at Stanford University. The term last spike has since been used to refer to a spike driven at the usually ceremonial completion of a railroad construction project, particularly one in which construction is undertaken from two origins toward a meeting point.

History

Completing the last link in the transcontinental railroad with a spike of gold was the brainchild of David Hewes, a San Francisco financier and contractor. The spike was manufactured in 1869 especially for the May event by the William T. Garratt Foundry in San Francisco. Two of the sides were engraved with the names of the railroad officers and directors. A special tie of polished California laurel was chosen to complete the line where the spike would be driven. The ceremony was planned to be held on May 8 (the date engraved on the spike), but it was postponed two days because of bad weather and a labor dispute that delayed the arrival of the Union Pacific side of the rail line.

On May 10, in anticipation of the ceremony, Union Pacific No. 119 and Central Pacific No. 60 (better known as the Jupiter) locomotives were drawn up face-to-face on Promontory Summit. How many people attended the event is unknown; estimates run from as few as 500 to as many as 3,000; government and railroad officials and track workers were present to witness the event. Before the last spike was driven, three other commemorative spikes, presented on behalf of the three other members of the Central Pacific's Big Four who did not attend the ceremony, had been driven into their places in a pre-bored laurel tie:

a second, lower-quality gold spike, supplied by the San Francisco News Letter, was made of what in 1869 was $200 worth of gold and inscribed: With this spike the San Francisco News Letter offers its homage to the great work which has joined the Atlantic and Pacific Oceans. a silver spike, supplied by the State of Nevada; forged, rather than cast, of 25 troy ounces (780 g) of unpolished silver a blended iron, silver, and gold spike, supplied by the Arizona Territory, engraved: Ribbed with iron clad in silver and crowned with gold Arizona presents her offering to the enterprise that has banded a continent and dictated a pathway to commerce. This spike was given to Union Pacific president, Oliver Ames, following the ceremony. The spike was donated to the Museum of the City of New York in 1943, by a descendant of Sidney Dillon. It was, for a time, on display at the Union Pacific Railroad Museum in Council Bluffs, Iowa. The Museum of the City of New York sold the spike in January 2023, via auction, to benefit other items in its collection. The winning bid totaled US$2.2 million The golden spike was made of 17.6-karat (73%) copper-alloyed gold, and weighed 14.03 troy ounces (436 g). It was dropped into a drilled hole in the ceremonial last tie and gently tapped into place with a ceremonial silver spike maul. The golden spike was engraved on all four sides:

The Pacific Railroad ground broken January 8, 1863, and completed May 8, 1869 Directors of the C. P. R. R. of Cal. Hon. Leland Stanford. C. P. Huntington. E. B. Crocker. Mark Hopkins. A. P. Stanford.

Chief Engr. May God continue the unity of our Country, as this Railroad unites the two great Oceans of the world. Presented by David Hewes San Francisco. The original golden spike was removed immediately after being hammered in, to prevent it from being stolen.

A duplicate golden spike, exactly like the one used in the ceremony (except for the date), was cast at the same time, but engraved at a later time and bearing the correct Promontory date of May 10, 1869. It has been noted that the first Golden Spike engraving appeared "rushed". The duplicate golden spike, the Hewes family spike, bears lettering that appeared more polished. Unknown to the public, the duplicate golden spike was held by the Hewes family until 2005. It is now on permanent display, along with Thomas Hill's 1881 painting The Last Spike, at the California State Railroad Museum in Sacramento. With the locomotives drawn so near, the crowd pressed so closely around Stanford and the other railroad officials that the ceremony became somewhat disorganized, leading to varying accounts of the events. On the Union Pacific side, thrusting westward, the last two rails were laid by Irishmen; on the Central Pacific side, thrusting eastward, the last two rails were laid by the Chinese! A. J. Russell stereoview No. 539 photograph shows the "Chinese at Laying Last Rail UPRR". Eight Chinese workers laid the last rail, and three of these men, Ging Cui, Wong Fook, and Lee Shao, lived long enough to participate in the 50th anniversary parade. At the conclusion of the ceremony, the participating Chinese workers were honored and cheered by the CPRR officials and that road's construction chief, J. H. Strobridge, at a dinner in his private railroad car. To drive the final spike, Stanford lifted a silver spike maul and drove the spike into the tie, completing the line. Stanford and Hewes missed the spike, but the single word "done" was nevertheless flashed by telegraph around the country. In the United States, the event has come to be considered one of the first nationwide media events. The locomotives were moved forward until their cowcatchers met, and photographs were taken. Immediately afterward, the golden spike and the laurel tie were removed, lest they be stolen. They were replaced with a regular iron spike and normal railroad tie. At exactly 12:47 pm, the last iron spike was driven, finally completing the line. After the ceremony, the Golden Spike used in the ceremony was donated to the Stanford Museum (now Cantor Arts Center) in 1898. The ceremonial laurel tie was destroyed in the fires caused by the 1906 San Francisco earthquake. A replica of the laurel tie, dedicated in late 2024, is on display in the Gravity Car Barn Museum on Mount Tamalpais.

Worked examples

Example 1 — a first encounter with Golden spike

Start with the simplest possible case. Write down what Golden spike claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Golden spike 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 Golden spike 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 Golden spike

In research
Golden spike appears in astronomy 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 Golden spike 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
Golden spike is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1869 in Utah Territory, 1869 in rail transport, 1869 in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Golden spike 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.
