WASHINGTON, July 8 — The transcontinental railroad cost an estimated $115 million to build. That figure, equivalent to roughly $2.5 billion in 2023 dollars, represents one of the largest single infrastructure investments in nineteenth-century America. The Central Pacific Railroad spent about $70 million of that total; the Union Pacific spent roughly $45 million.
The federal government put up $64 million in 30-year, 6% bonds. It also granted 130 million acres of public land, which the railroads sold to raise capital.
Those numbers tell the story of a project that was as much a government enterprise as a private one.
By the numbers: the cost of connection
The bottom line is that the railroad’s completion remade the American economy. It opened the West to settlement, agriculture, mining, and ranching on a scale previously unimaginable. The value of agricultural land in the West increased dramatically as the railroad made it possible to ship goods to eastern markets.
Investors will note the specific industries that the railroad unlocked. The line enabled the shipment of cattle from Texas to Chicago, which fueled the cattle boom of the 1870s through the 1880s.
The railroad also facilitated the extraction of minerals, including silver from the Comstock Lode — discovered in 1859 — and copper from Montana. Those resource flows built fortunes and transformed regional economies. The figure that matters for employment: the railroad’s construction and operation created thousands of jobs.
It stimulated entire industries — steel, coal, and lumber — that supplied the tracks, the locomotives, and the ties. The railroad was not merely a transportation project; it was a catalyst for industrial expansion across multiple sectors.
The dark ledger: displacement and destruction
But the economic gains came with a brutal cost that no bond coupon can capture. The railroad led directly to the displacement of Native American tribes from their ancestral lands. The construction crews and later the settlements that followed the tracks pushed indigenous peoples off territory that had been theirs for centuries.
The American bison were hunted to near-extinction. The animals were killed to supply railroad workers with food, and later for their hides.
The railroad made it possible to ship bison hides east in commercial quantities, and the slaughter accelerated dramatically once the tracks were laid. That is the other side of the economic ledger — one that historians still debate. The railroad created wealth, but it also destroyed ways of life and drove a species to the brink of extinction.
The same infrastructure that built Chicago’s stockyards also emptied the Great Plains of bison.
Corruption on the line
The railroad’s financial structure was plagued by corruption. The most notable scandal was the Crédit Mobilier affair of 1872. Union Pacific insiders created a separate construction company — Crédit Mobilier — and used it to overcharge the railroad for construction work.
They then bribed members of Congress to look the other way. The scandal broke into public view during the 1872 presidential election campaign.
It implicated sitting members of Congress, including the future president James A. Garfield, who was then a representative from Ohio. The affair became a symbol of the Gilded Age’s casual mingling of corporate profit and political power.
The federal government had provided $64 million in bonds and 130 million acres of land. Some of that public money ended up in the pockets of the insiders who had rigged the construction contracts.
The Union Pacific itself was left with inflated costs and a damaged reputation.
What to watch next
The transcontinental railroad’s legacy is still being debated 150 years later. The economic transformation it enabled is undeniable — the West was settled, industries were built, and the United States became a continental power. But the human and environmental costs were enormous, and the corruption that accompanied the project set patterns that would recur in later infrastructure booms.
Investors will note that the railroad’s financial structure — government bonds combined with land grants and private capital — became a template for later transportation projects. The question that remains is whether the benefits of such projects can be achieved without the displacement, destruction, and graft that accompanied the first transcontinental line.
The numbers from 1869 suggest that is a hard balance to strike.
