How America Built 1,000 Miles of Railroad Through Mountains Before Bulldozers

On January 8th, 1863, a significant event unfolded at a muddy ceremony in Sacramento, California, where a crowd gathered to witness Governor Leland Stanford drive a ceremonial silver spike into a railroad tie.

This moment marked the official beginning of construction for the Central Pacific Railroad.

The goal was both audacious and daunting: to build a railroad stretching east from Sacramento, crossing the Flat Valley, ascending the Sierra Nevada mountains, traversing Nevada, and crossing the arid desert to connect with the Union Pacific Railroad, which was building westward from Omaha.

The two lines would converge somewhere in the middle, creating the first transcontinental railroad—a continuous iron pathway spanning the entire width of the United States.

While the Union Pacific had a relatively easier route through flat prairie and wide-open terrain, the Central Pacific faced the formidable Sierra Nevada.

This mountainous region presented a wall of granite rising 7,000 feet high, blanketed in snow for eight months each year, and characterized by steep slopes so treacherous that a man standing upright had to lean forward to avoid falling backwards.

The engineers discovered that there were no natural passes at the right elevation; thus, the railroad would have to be meticulously carved into the mountains using only hand tools, black powder, and sheer human labor.

The men who undertook this monumental task—chipping tunnels through solid rock and constructing trestles over bottomless canyons—were primarily Chinese immigrants, Irish laborers, and a handful of Civil War veterans who had survived one kind of hell only to enter another.

Between 1863 and 1869, these laborers would move more rock and dirt than had been moved in any previous construction project in American history.

They would build over 1,000 miles of railroad through terrain that many engineers deemed impossible, all without the aid of engines, machinery, bulldozers, or excavators.

Instead, they relied on shovels, pickaxes, wheelbarrows, black powder, and hands that bled until they became calloused.

This is the story of how America built the transcontinental railroad—not the sanitized version that glosses over the suffering and sacrifice, but the raw, unfiltered truth.

It is about the men who froze to death in snow tunnels, those who were blown apart by premature explosions, and the countless souls whose names were never recorded, their graves unmarked cuts in the Sierra granite.

This narrative reveals the scale, suffering, and relentless labor that reshaped a continent, one shovel full of dirt at a time.

To understand the enormity of the challenge, we must first examine the Sierra Nevada itself.

The Sierra Nevada is a granite batholith, a massive intrusion of igneous rock that cooled and solidified millions of years ago.

Unlike sedimentary stone, which can be chipped away with a pickaxe, granite is dense and crystalline, often harder than steel.

A laborer swinging a sledgehammer against Sierra granite could toil all day and only make a dent measured in inches.

However, the Central Pacific needed tunnels—15 tunnels, some extending over 1,600 feet long, to be exact—cut through solid rock at elevations exceeding 7,000 feet.

The longest of these, the Summit Tunnel, would have to bore through 1,659 feet of granite at an altitude where snow fell from October through May, and temperatures plummeted to 20 degrees below zero.

Despite the daunting task, engineers were aware it was theoretically possible.

Tunnels had been constructed through mountains in Europe using similar methods, but those projects had taken decades to complete.

The Central Pacific, however, was under immense pressure.

Investors were eager for returns, competition from the Union Pacific was fierce, and a federal charter incentivized them to complete the railroad quickly, paying them per mile of track laid.

The faster they built, the more money they earned.

Led by engineers such as Theodore Judah and later Samuel Monagu, the Central Pacific devised a plan: hire as many men as possible, work around the clock, and accept that some would not survive.

Initially, the workforce was diverse, comprising Irish immigrants fleeing famine, Civil War veterans seeking employment, drifters, and miners who had failed in the gold fields.

However, the work was grueling, and while the pay was decent, it often wasn’t enough to retain laborers.

Men would sign on, endure a few weeks of the brutal conditions, and quit.

By 1864, the Central Pacific was in dire need of labor, prompting Charles Crocker, one of the four primary investors and the construction overseer, to make a pivotal decision.

He began hiring Chinese workers, many of whom were veterans of the gold rush, having been pushed out of mining camps due to racial violence and restrictive laws.

These Chinese immigrants often found work in restaurants and agriculture, earning lower wages than their white counterparts and lacking legal protections.

Crocker recognized their potential as a resource—available, inexpensive, and, contrary to the racist assumptions of the time, they proved to be the most effective laborers on the project.

Within a year, over 90% of the Central Pacific workforce consisted of Chinese laborers, peaking at more than 12,000 men at the height of construction.

These workers performed the most arduous and perilous tasks, blasting tunnels, erecting retaining walls, and grading roads on steep slopes where men were roped together to prevent falls.

They undertook these challenges for less pay and in harsher conditions than any white worker would accept.

The nightmare of tunnel work epitomized the dangers they faced.

Boring through granite with 1860s technology was an exercise in tedium and peril.

There were no tunnel boring machines or pneumatic drills; the method was simple yet brutal.

Laborers drilled holes into the rock face using hand drills, packed them with black powder, lit the fuse, and ran.

After waiting for the explosion, they cleared the rubble and repeated the cycle.

A single round of drilling, blasting, and clearing might advance the tunnel face by a mere 18 inches, or perhaps 2 feet if the rock cooperated.

The Summit Tunnel, measuring 1,659 feet long, was attacked from both ends and from a central shaft sunk from above.

Even with four teams working simultaneously, progress was measured in feet per week.

Drilling crews operated in teams of three, with one man holding the steel drill—a long iron rod with a chisel tip—while the other two swung sledgehammers in alternating rhythm.

Strike, turn the drill a fraction, strike again—this was the relentless routine, hour after hour.

The noise within the tunnel was deafening, the ringing of steel on steel echoing off the granite walls.

The air grew thick with rock dust, coating their lungs and leaving them coughing blood by the end of each shift.

These laborers worked by candlelight or oil lamps, with poor ventilation.

The smoke from the lamps mingled with the dust, making breathing a challenge.

This was all before the blasting began.

Once a series of holes had been drilled—usually six to ten per round—the blasting crew took over.

Black powder was packed into the holes using wooden tamping rods, and a fuse was inserted, cut to length based on the time needed to clear the area—typically 60 to 90 seconds.

However, fuses were unpredictable; they could burn fast or slow, sputter out, or ignite faster than anticipated.

The blasting crew lit the fuses, starting from the farthest from the tunnel entrance and working their way back, lighting each one in sequence before fleeing the tunnel to wait for the explosions.

The blasts were violent, and the confined space of the tunnel amplified the shock wave.

Even outside the tunnel, the concussion could be felt in the chest, but inside, if caught in the blast, a man could suffer ruptured lungs, shattered eardrums, or be buried under tons of rock.

Premature explosions claimed lives.

A fuse burning faster than expected, a spark from a hammer strike igniting loose powder—these were all too common.

In September 1866, a premature blast in the Summit Tunnel killed four Chinese workers instantly, their bodies buried under rubble.

It took two days to recover them.

Company records listed them simply as Chinese laborers, their names unknown.

They were buried in a mass grave near the tunnel entrance, and work resumed the following day.

After each explosion, clearing crews moved in to remove the rubble, broken rock, and granite fragments by hand.

Men with shovels and wheelbarrows transported the debris, which was loaded into small carts, pushed out of the tunnel on temporary rails, and dumped over the mountain’s edge.

A single blast could generate 20 to 30 tons of rubble, all of which had to be cleared before work could continue.

The exhausting cycle of shoveling, loading, pushing, dumping, and repeating continued shift after shift.

The Summit Tunnel took over two years to complete—a grueling two years of continuous work, drilling, blasting, and clearing.

And that was just one of the 15 tunnels.

Each required the same arduous processes, the same labor, and the same risks.

Yet, the men undertaking this work were paid only $30 a month—approximately one dollar a day.

In contrast, white workers earned $35 a month plus room and board, while Chinese workers were required to purchase their own food.

They lived in camps near the work sites, crude shelters made from scrap lumber and canvas.

They cooked their meals, typically rice and dried fish, over open fires.

During winter, when the snow reached depths of 20 feet, the camps became buried.

The workers lived and labored in tunnels dug through the snow, some of which collapsed, burying men alive.

The winter of 1866 to 1867 was one of the harshest on record, with snow falling continuously from November through March.

At the summit, the snowpack reached 40 feet in places, and avalanches were a constant threat.

An avalanche offered no warning; one moment the snow was stable, and the next, the entire slope would slide, carrying men, equipment, and camps with it.

In February 1867, an avalanche swept through a Chinese labor camp near Donner Pass, burying the camp under 30 feet of compacted snow.

Estimates of the number of men in the camp range from 20 to 40, and their bodies were never recovered.

When the snow melted in June, remains were found scattered across the slope, and they were buried where they lay, without markers or names.

Yet, the work persisted.

The Central Pacific continued to push forward, bringing in more workers, rebuilding camps, and advancing tunnels foot by foot.

Slowly, against all odds, the railroad took shape.

East of the summit, the terrain opened up, shifting the focus from tunneling to grading.

Grading involved creating a level road for the tracks.

In flat terrain, this task was relatively straightforward—clear the brush and lay the ties.

However, in the mountains and across Nevada, the landscape was far from flat.

The roadbed had to be carved into hillsides, built up across gullies, and bridged over canyons.

Cutting a roadbed into a hillside was accomplished using picks and shovels.

A crew would mark the line of the grade and begin digging.

On the uphill side, they would cut into the slope, removing dirt and rock to create a level shelf.

On the downhill side, they would build up a retaining wall using the excavated material.

If the slope was steep, the retaining wall had to be reinforced with timber or stone to prevent collapse.

This work was slow; a crew of 50 men might advance the grade by only a few hundred feet in a day.

The Chinese workers excelled at this meticulous work, constructing retaining walls that have withstood the test of time, standing strong even after 150 years.

These dry stone walls were fitted together without mortar, designed to flex and settle without collapsing.

They graded roads on slopes where a misstep could result in a fall of hundreds of feet, working roped together, anchored from above, chipping footholds into the rock while hauling materials up and down using pulleys and woven baskets.

The techniques they employed mirrored those used in building terraces in the mountains of southern China, adapted to the unique challenges of the Sierra Nevada.

On the flat lands of Nevada, the challenges shifted once more.

The terrain transformed into a desert, with alkaline soil, a lack of water, and summer temperatures exceeding 110 degrees Fahrenheit.

The predominantly Chinese workforce graded hundreds of miles of roadbed across this desolate landscape.

They lived in temporary camps that moved with the work, hauling in water by wagon from distant wells.

Food supplies arrived via wagon train from Sacramento, a journey that could take weeks.

The camps were brutal, plagued by dust storms, scorpions, rattlesnakes, and oppressive heat.

Men succumbed to heat stroke, dehydration, and accidents.

The company did not maintain detailed records of deaths, so the exact number remains unknown.

Estimates suggest that over 1,000 Chinese workers perished during the construction of the Central Pacific line, with some dying from accidents, others from disease, and many from exposure.

Their graves, if they were buried, have been lost to time.

As the Central Pacific struggled through the mountains, the Union Pacific was racing west across the plains.

The Union Pacific’s labor force consisted predominantly of Irish immigrants, Civil War veterans, and freed slaves.

While their challenges differed, they were equally brutal.

The plains were flat but desolate, lacking timber for construction and stone for ballast.

Everything had to be transported in.

Native American tribes, including the Lakota, Cheyenne, and Pawnee, viewed the railroad as an invasion—and they were right.

The railroad brought settlers, soldiers, and buffalo hunters who decimated the herds upon which the tribes depended.

The tribes fought back, raiding work camps, tearing up rails, and attacking supply trains.

In response, the Union Pacific hired guards, many of them former soldiers, to protect the workers.

The construction process became a slow-moving war.

Grading crews on the Union Pacific faced their own set of dangers.

Accidents involving black powder, floods that washed away miles of roadbed, and harsh winters with temperatures plummeting below zero all contributed to the perilous conditions.

Men froze to death in their tents, while others fell victim to disease.

Cholera and dysentery swept through the camps, claiming dozens of lives.

Despite these challenges, the company pressed on.

Competition with the Central Pacific was fierce; every mile of track translated into money, land grants from the federal government, and prestige.

By 1868, both railroads were making rapid strides.

The Central Pacific had cleared the Sierra Nevada and was laying track across Nevada at a pace exceeding one mile per day.

Meanwhile, the Union Pacific pushed through Wyoming, heading toward Utah.

The two lines were converging, and the race to completion became a national spectacle.

Newspapers covered the competition, and bets were placed on where the lines would meet.

As workers realized the project was nearing completion, they intensified their efforts.

On April 28th, 1869, the Chinese crews on the Central Pacific set a record by laying 10 miles of track in a single day.

Ten miles—that equated to over 3,000 ties placed, more than 25,000 spikes driven, and 50,000 pounds of rail lifted, positioned, and secured.

The feat demanded coordination, speed, and endurance that seemed impossible, yet it was accomplished.

The record stood.

On May 10th, 1869, the two railroads met at Promontory Summit, Utah.

A crowd gathered, including dignitaries from both companies, photographers, and reporters.

The ceremony featured speeches, handshakes, and the driving of a golden spike to symbolize the completion of the transcontinental railroad.

However, the photographs from that day tell a different story.

They display well-dressed men in suits posing in front of the locomotives, but they do not include the Chinese workers.

Despite having constructed more than half of the Central Pacific line and having performed the hardest and most dangerous tasks, they were excluded from the celebration.

The official narrative erased their contributions.

The celebration belonged to the investors, engineers, and white workers, while the Chinese laborers returned to their camps, packed their tools, and dispersed.

Most returned to California, while others found work maintaining the line or moved on to new construction projects.

Their contributions remained forgotten for decades.

Yung Wing, Hungwa, Chin, Linso—these are among the very few names recorded of the thousands of Chinese workers who built the railroad.

Most were simply listed as Chinese laborers in company records, devoid of first names, ages, or hometowns.

When they died, their bodies were often buried in mass graves or shipped back to China if their families could afford it.

The Central Pacific maintained minimal records of these deaths, as there was no legal requirement for reporting.

There was no oversight, no accountability; the men were expendable, and they understood this reality.

If you believe the memory of these men—the laborers who blasted tunnels through granite and laid tracks across deserts—matters, consider subscribing.

No one documented their sacrifices, but we are now, ensuring that these men—Chinese, Irish, Black—are never forgotten.

This is not merely about witnessing history; it is about honoring it.

The construction of the transcontinental railroad claimed an estimated 1,500 to 2,000 workers’ lives, though the exact number will remain unknown due to the companies’ lack of comprehensive records.

Graves are scattered across the vast expanse of mountains, plains, and deserts, with some marked but most unmarked.

The railroad they built transformed the United States, connecting the coasts and reducing travel time from six months by wagon to merely six days by train.

It enabled the settlement of the West and facilitated the rapid movement of goods, people, and ideas.

Yet, this monumental achievement was built predominantly by hand.

The tools employed in constructing the transcontinental railroad were simple: shovels, pickaxes, sledgehammers, wheelbarrows, hand drills, and black powder.

No steam shovels or mechanical excavators were available; the first steam-powered construction equipment would not emerge for another decade.

Every cubic yard of earth moved, every foot of tunnel blasted, and every rail spike driven was accomplished through sheer human effort.

The scale of this undertaking is staggering.

Over 20 million cubic yards of earth were moved during the construction of the Central Pacific line alone—enough to fill a trench 10 feet deep and 10 feet wide from San Francisco to New York.

This monumental task was executed one shovel full at a time.

Engineering challenges were addressed through a combination of ingenuity and brute force.

The trestles, wooden bridges that carried the tracks over canyons and ravines, were constructed using timber hauled from hundreds of miles away.

These trestles were massive structures, some exceeding 100 feet in height, built on slopes where a misplaced timber could lead to disaster.

Chinese workers excelled in this endeavor, constructing architectural marvels using mortise and tenon joints, wooden pegs, and hand-cut timbers.

Many of these original wooden trestles were later replaced with stone or steel, yet some stood for decades.

Finally, in November 1867, after two years of relentless work, the Summit Tunnel—the longest and most challenging tunnel on the Central Pacific line—was completed.

When the final blast broke through, connecting the east and west faces, the alignment was nearly perfect.

The two bores, started from opposite sides of the mountain and guided only by surveying and mathematics, met with less than 2 inches of error over a span of 1,659 feet.

It was a remarkable feat of engineering, accomplished by men wielding hand drills and black powder.

However, the human cost of this triumph was inscribed in the bodies of those who perished.

The Central Pacific estimated that over 1,000 Chinese workers died during the construction, equating to one death for roughly every mile of track.

The Union Pacific’s toll was lower, estimated at 400 to 500, but still significant.

These fatalities were not mere accidents; they resulted from pushing men to work faster than was safe in inherently dangerous conditions, with no safety equipment or oversight.

The companies were aware that men would die, accepting it as a cost of doing business.

The workers had no choice.

For Chinese immigrants, the railroad was one of the few employers willing to hire them amid pervasive anti-Chinese sentiment in California.

They were excluded from most trades, barred from testifying in court, and subjected to violence and discrimination.

The railroad offered wages, albeit meager, and a chance at survival.

For Irish workers on the Union Pacific, the situation was similar.

Fleeing famine and prejudice, they took the work because there were no alternatives.

Freed slaves working on the line sought to escape the sharecropping system of the post-Civil War South.

Although the railroad was brutal, it provided cash—a necessity for men with few options.

The legacy of the transcontinental railroad is complex.

It stands as an engineering marvel that transformed the economy, facilitated the growth of cities, expanded agriculture, and spurred the industrialization of the West.

Yet, it was built upon exploitation, relying on the labor of men treated as disposable, and it contributed to the destruction of Native American lands and ways of life.

The railroad ushered in settlers who displaced tribes and brought buffalo hunters who slaughtered herds to the brink of extinction.

It marked the end of a way of life that had existed for millennia.

The tribes understood the implications of the railroad and fought against it, but ultimately, they lost.

The physical remnants of the construction still exist today.

In the Sierra Nevada, hikers can explore the sites of old tunnels, some still in use, widened and reinforced, while others are abandoned, sealed off, and slowly reclaimed by the mountains.

The graded roadbed, carved into the hillsides, remains recognizable, overgrown with trees and brush.

Retaining walls built by Chinese workers 150 years ago still stand, fitted so precisely that they have not shifted.

In Nevada and Utah, the old grade is visible from the air—a scar running across the desert, parallel to modern tracks.

The wooden ties have long since rotted, and the rails have been salvaged and reused, but the shape of the roadbed remains intact.

Scattered along the line are the graves of those who perished.

Small markers and forgotten cemeteries, piles of stones in the desert, indicate where workers were buried in place, never relocated.

Some of these graves have been identified and documented by historians and archaeologists, while many others remain unmarked and unknown.

Photographs from the era, although fragmentary and incomplete, capture the scale of the work.

They show Chinese workers standing in tunnels, holding drills and hammers, their faces obscured by shadows and the limitations of early photography.

Images of grading crews depict dozens of men wielding shovels as they labor on a hillside, while shots of trestles under construction reveal timber frameworks rising from canyons, dwarfing the men who built them.

These images provide a glimpse into the past, but they do not convey the deaths, suffering, cold, heat, or exhaustion endured by the workers.

Yet they do show the men, and that is something significant.

The engineers who designed the transcontinental railroad are remembered: Theodore Judah, Grenville Dodge, their names etched on plaques and monuments.

The investors—the Big Four: Leland Stanford, Collis Potter Huntington, Mark Hopkins, and Charles Crocker—amassed fortunes and founded universities, their names adorning buildings across California.

Yet, the workers—the men who physically constructed the railroad—remain largely forgotten.

A few monuments exist; in 2014, the U.S. Department of Labor inducted Chinese railroad workers into the Labor Hall of Honor, placing a plaque and delivering speeches.

However, for over a century, their contributions were systematically erased.

Historians are working to recover these stories through oral histories from descendants, fragmentary company records listing work crews and casualties, and archaeological efforts at old campsites to uncover artifacts and personal items.

Slowly, the picture is being pieced together, though much has already been lost.

The workers themselves rarely spoke of their experiences.

For them, it was just work—hard, dangerous work.

They did it, survived, and moved on.

There was no expectation of recognition or gratitude, and for over a century, there was none.

The transcontinental railroad remains in operation today.

The route has been modified, tunnels improved, and grades eased, yet the bones of the original line endure.

Freight trains still transport goods from California’s ports to eastern markets, following the path carved out by Chinese and Irish laborers in the 1860s.

The infrastructure they built has facilitated commerce for over 150 years, constructed without bulldozers, excavators, or any machinery we now consider essential for construction.

Instead, it was built with hand tools, black powder, and human labor pushed to the absolute limit of endurance.

The men who built the transcontinental railroad did not expect to be remembered.

Most likely, they did not perceive their work as remarkable.

It was a job that paid, albeit brutally and dangerously.

But so were all the other options available to men with no education, capital, or connections.

They undertook the work because it needed doing, and they were willing to do it.

They moved millions of tons of rock and dirt, blasted 15 tunnels through the Sierra Nevada, graded a roadbed across 1,000 miles of mountains, plains, and deserts, and laid over 1,700 miles of track—all while connecting a nation.

The cost of this monumental achievement was over 1,500 lives.

The legacy is the railroad itself, and the lesson—if there is one—is that the infrastructure we depend on, the systems we often take for granted, were built by people whose names we do not know, performing work we can scarcely imagine for wages that barely kept them alive.

They built America with shovels, hand drills, and their own two hands.
