Union Pacific No. 119

Union Pacific No. 119 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 Union Pacific No. 119 rather than just read about it. In short: Union Pacific 119 is a 4-4-0 "American" type steam locomotive made famous for meeting the Central Pacific Railroad's Jupiter at Promontory Summit, Utah, during the Golden Spike ceremony commemorating the completion of the first transcontinental railroad in 1869. The locomotive was built for the Union Pacific Railroad by Rogers Locomotive and Machine Works of Paterson, New Jersey, in 1868, along with numbers 116, 117…

Key takeaways

Union Pacific No. 119 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Union Pacific No. 119 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Union Pacific No. 119 from memory before moving on to harder problems.

Reference excerpt

Union Pacific 119 is a 4-4-0 "American" type steam locomotive made famous for meeting the Central Pacific Railroad's Jupiter at Promontory Summit, Utah, during the Golden Spike ceremony commemorating the completion of the first transcontinental railroad in 1869. The locomotive was built for the Union Pacific Railroad by Rogers Locomotive and Machine Works of Paterson, New Jersey, in 1868, along with numbers 116, 117, 118 and 120. The original was scrapped in 1903, but a replica now operates at the Golden Spike National Historical Park.

Promontory Summit No. 119 was assigned to the Union Pacific Railroad's Utah Division, carrying trains between Rawlins, Wyoming, and Ogden, Utah, and was stationed in the latter when a call for a replacement engine came from vice-president Thomas C. Durant, to take him to Promontory Ridge, Utah Territory, for the Golden Spike ceremony celebrating the completion of the Transcontinental Railroad. While enroute to the ceremony, a swollen river had washed away some supports to the Devil's Gate Bridge. Durant's engineer refused to take his engine across, consenting only to nudging the lighter passenger cars over the span. It held, but this left Durant and his entourage without an engine. No. 119 was sent from Ogden to take them the short distance to Promontory, where it was memorialized in photos and history faced nose to nose with the Central Pacific's Jupiter. In Andrew J. Russell's famous photograph of the Meeting of the Lines, No. 119 is seen on the right with its engineer, Sam Bradford, leaning off the cowcatcher holding a bottle of champagne up to Jupiter engineer George Booth. Bradford and Booth would later break a bottle of champagne over the other's locomotive in celebration.

Later career After the Golden Spike run, No. 119 led a similar life to Jupiter, and returned to service as a freight locomotive. In 1882, 119 was renumbered to 343, and was scrapped in 1903.

Worked examples

Example 1 — a first encounter with Union Pacific No. 119

Start with the simplest possible case. Write down what Union Pacific No. 119 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 Union Pacific No. 119 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 Union Pacific No. 119 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 Union Pacific No. 119

In research: Union Pacific No. 119 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 Union Pacific No. 119 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: Union Pacific No. 119 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 Union Pacific No. 119 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.
