Промонтoрий: Место соединения первой трансконтинентальной железной дороги США

Area of high ground in Box Elder County, Utah

Promontory is an area of high ground in Box Elder County, Utah, United States, 32 mi (51 km) west of Brigham City and 66 mi (106 km) northwest of Salt Lake City. Rising to an elevation of 4,902 feet (1,494 m) above sea level, it lies to the north of the Promontory Mountains and the Great Salt Lake. It is notable as the location of Promontory Summit, where the First transcontinental railroad from Sacramento to Omaha in the United States was officially completed on May 10, 1869. The location is sometimes confused with Promontory Point, a location further south along the southern tip of the Promontory Mountains. Both locations are significant to the Overland Route: Promontory Summit was where the original, now abandoned, alignment crossed just north of the Promontory Mountains; while Promontory Point is where the modern alignment, called the Lucin Cutoff, crosses the southern tip of the Promontory Mountains. By the summer of 1868, the Central Pacific (CP) had completed the first rail route through the Sierra Nevada mountains, and was now moving down towards the Interior Plains and the Union Pacific (UP) line. More than 4,000 workers, of whom two thirds were Chinese, had laid more than 100 mile (161 km) of track at altitudes above 7000 feet (2134 m). In May 1869, the railheads of the Union Pacific and the Central Pacific railroads finally met at Promontory Summit, Utah Territory.

Promontory Summit, Utah Territory, had been agreed upon as the point where the two railheads would officially meet, following meetings in Washington, D. C., in April 1869, where it was also agreed that a ceremony would be held to drive in the Last Spike to commemorate the occasion. However, the original date of May 8 had to be postponed for two days because of bad weather and a labor dispute on the Union Pacific side. Over 400 laid off unpaid graders and tie cutters chained U. P. R. R. Vice President Thomas Durant's dignitary railcar to a siding in Piedmont, Wyoming, until he wired for money to pay them. After almost a two day delay, when Durant's train arrived at the Devil's Gate Bridge in Wyoming, floodwaters turned a mild creek into a raging torrent, which threatened to collapse the railroad bridge. The engineer would not take his locomotive, whose number is lost to history, across the rickety structure, but he gave each of the passenger cars a hefty heave. The cars coasted across, but Durant no longer had a way to get to Promontory. A hasty telegraph to Ogden, Utah Territory, sent Union Pacific's engine "119" to the rescue. After a hearty party in Ogden the night of May 9, the dignitaries arrived at Promontory Summit on the morning of May 10, where the Golden Spike Ceremony was finally planned and took place, with the last iron spike driven at 12:47 PM. The trains carrying the railroads' officials were drawn by Union Pacific's No. 119 and Central Pacific's No. 60 (officially named the Jupiter) locomotives, neither of which had been originally chosen for the ceremony. The Central Pacific had originally chosen their no. 29 Antelope to attend the ceremony, while the Union Pacific had also chosen another, unidentified engine for their train, but both engines encountered mishaps en route to the ceremony. On May 10,

The event at Promontory Summit was billed as the "wedding of the rails" and was officiated by the Reverend John Todd. In 1898, the golden 'Hewes' spike was donated to the Leland Stanford Junior University Museum. In one account, the second Golden Spike and the Laurelwood Tie were destroyed in the 1906 San Francisco earthquake and fire, which also destroyed the San Francisco Newsletter Newspaper Offices where these artifacts were on display. In Union Pacific's account, the location of the "second, lower quality golden spike faded into obscurity". Stanford University loaned the original 1869 gold spike to Cecil B. DeMille for the film Union Pacific (1939). It was held aloft in the scene commemorating the actual event, although a brass prop was used for the hammering sequence. The only marks on The Golden Spike were caused by a Union Army Officer who struck the Spike with the pommel of his sword four times on the ride back to California. Nobody tried to fully drive 17.6 Carat Solid Gold Spikes or any of the precious metal spikes into a wooden tie. Four holes had been drilled into the Laurelwood tie to "hold" the spikes while Stanford and UPRR's Thomas Durant gently tapped them before the Spikes and the Laurelwood Tie were removed to make way for a regular pine wood tie and four regular iron spikes, the last one was wired to the Transcontinental Telegraph Line. Stanford and Durant were supposed to strike the last iron spike with a regular iron spike hammer, also wired to the Telegraph Line, to send a signal from coast to coast as the job was done. Stanford missed the Spike, hitting the wooden tie instead; however, the telegraph operator hit his key as though Stanford had hit the spike. Durant missed the spike and the tie entirely; but likewise, the operator hit his key so the Nation would not know the difference. Then the operator sent the message D O N E! With the railroad's completion, a trip across the Nation went from up to six months on foot, on an animal, or in an animal pulled wagon to as little as eight days from city of New York, via railroads and ferries, to San Francisco. Promontory Summit marks the site where the First Transcontinental Railroad was completed May 10, 1869, from Omaha to Sacramento, but not "from the Missouri river to the Pacific" as called for by the Pacific Railroad Act of 1862. Western Pacific completed the final leg from Sacramento to San Francisco Bay on September 6, 1869, with the last spike at the Mossdale Bridge spanning the San Joaquin River near Lathrop, California. Passengers had to cross the Missouri River by boat between Council Bluffs, Iowa, and Omaha, Nebraska, until the Union Pacific Missouri River Bridge was built in March 1872. In the meantime, the first uninterrupted coast to coast railroad was established in August 1870 at Strasburg, Colorado, with the completion of the Denver extension of the Kansas Pacific Railway.

Promontory was the site of Promontory City during and shortly after the construction of the transcontinental railroad. However, by December 1869, the shops, tents, and store fronts were being dismantled as the traders and merchants moved to other towns. As trains became longer and heavier, additional engines were often required to pull them along the winding curves and up steep grades to the Promontory summit. This changed when the Southern Pacific, which had acquired Central Pacific operations in 1885, built a wooden railroad trestle across the Great Salt Lake between Ogden and Lucin, between February 1902 and March 1904. The 102.9 mile (166 km) Lucin Cutoff completely bypassed Promontory Summit. The last regularly scheduled transcontinental passenger train to pass through Promontory station was on Sunday, September 18, 1904. When the Great Depression led to a dramatic fall in revenues from railroad traffic, the Southern Pacific decided to abandon the line when it failed to meet its operating costs. On September 8, 1942, an "unspiking" ceremony was held to commemorate the lifting of the last rail over Promontory Summit; the old steel rails were used for the war effort in World War II.

By the early 1950s, a number of re enactments of the driving of the last spike had been held at Promontory Summit. The renewed interest led to a concerted effort to save the historic site. In 1957, local campaigners succeeded in getting the area recognized by the federal government, but without federal land ownership. The Southern Pacific, which still owned the right of way, agreed to give its holdings to the federal management. On July 30, 1965 the Act for the Golden Spike National Historic Site was signed into law. The area is administered by the National Park Service. and reference to similar engines of the time. The park, which has a visitor center and an engine house, is open throughout the year. Several walking trails and audio driving tours allow visitors to see the old cuts along the permanent way, highlighting the effort needed to construct the railroad over Promontory Summit. On every Saturday and holiday between May 1 and Labor Day, the two replica locomotives are lined up to re enact the "Golden Spike" ceremony. On the 150th anniversary of the completion of the railroad on May 10, 2019, the contributions of the 15,000 Chinese railroad workers were finally acknowledged. Records of the Chinese railroad workers had not been kept and it is believed thousands of people died laying those tracks due to the treacherous territory, including having to cut through the cold of the Sierra Nevada mountain range and the heat of the desert. Many descendants of the Chinese workers were at Promontory Summit for the occasion. A traditional Chinese lion dance opened the ceremony. The U. S. Secretary of Transportation, Elaine Chao (the first person of Chinese descent to hold the position), paid tribute to those Chinese workers.
