Montana Railroads
Updated: February 24, 2026
From Rivers to Railroads
Before railroads reached Montana, people mostly traveled and shipped goods by steamboat on the Missouri and Yellowstone Rivers and by wagon over rough trails.
These early routes were slow, could not be used year-round, and made it hard for Montana towns to trade with the rest of the United States.
Telegraphs, Towns, and New Ideas
A telegraph line linked Virginia City, Montana, with Salt Lake City, Utah, as early as 1866, allowing people to send quick messages across long distances.
By 1910, a network of railroads crossed Montana, and these lines played a major role in growing the state?s mining, ranching, and timber industries.
Why Railroads Were So Important
After the Civil War, railroad companies focused on building lines to the far West, and people in Montana Territory strongly wanted rail connections.
Ranchers needed railroads to ship cattle and sheep to distant markets, miners needed them to bring in heavy machinery and send out ore, and town leaders hoped trains would bring more settlers and businesses.
In the 1880s, new rail lines helped make Montana one of the world?s leading copper mining areas, and this booming economy helped Montana become a state in 1889.
Transcontinental Railroad Dreams
People in the United States imagined a transcontinental railroad crossing the whole country even before the Civil War, but disagreements between North and South delayed the project.
In 1869, the Union Pacific and Central Pacific railroads joined their tracks at Promontory Summit in Utah Territory, completing the first rail line from Omaha to Sacramento and then to the Pacific coast.
In 1864, Congress chartered the Northern Pacific Railroad to build another transcontinental line from Minnesota to the Pacific Northwest, but money problems and the Panic of 1873 slowed construction and caused bankruptcy.
Many people in Montana feared they would be left out of the new rail network and cut off from major trade and travel routes.
The First Railroad into Montana
While the Northern Pacific struggled, the Utah and Northern Railroad started building north from Utah toward the rich mining districts of southwestern Montana.
The Utah and Northern was a narrow-gauge line that began as a local Mormon project and was later taken over and pushed forward by the larger Union Pacific system.
The first rails into Montana Territory crossed Monida Pass on May 9, 1880, bringing year-round railroad service across the Continental Divide into the territory.
On the evening of December 21, 1881, the first Utah and Northern train reached the Butte area, carrying passengers and heavy mining equipment into what was becoming a major copper mining city.
This line gave Montana its first dependable, all-season rail connection and helped launch a major mining boom.
The Northern Pacific Arrives
As the Utah and Northern line advanced, the Northern Pacific Railroad also continued building its own transcontinental route across the northern United States.
The Northern Pacific's main line across Montana was completed in the early 1880s, connecting places like Glendive, Billings, Bozeman, Helena, and Missoula to the Great Lakes and the Pacific Coast.
The Northern Pacific later built the "Butte short line," finished in 1889, which branched off west of Bozeman, crossed Homestake Pass, and ran through Butte before rejoining the main line near Garrison.
To operate some shared track between Butte and Garrison, the Northern Pacific and Union Pacific created the Montana Union Railway in 1886, and the Northern Pacific eventually took control of that line.
More Railroads Cross the State
By the early 1900s, several major railroad companies served Montana, connecting it to many parts of the United States.
The Great Northern Railway built a line across northern Montana along the Hi-Line and became known for carrying passengers to Glacier National Park.
The Chicago, Milwaukee, St. Paul and Pacific Railroad, often called the Milwaukee Road, entered Montana in 1907 and finished its own line to the Pacific Ocean by 1909.
The Milwaukee Road became famous for electrifying parts of its main line in Montana and Idaho in the 1910s so electric locomotives could handle steep mountain grades more efficiently than steam engines.
How Railroads Changed Montana
Railroads shrank travel times from days or weeks to just hours between many Montana towns and distant cities.
Trains carried in food, coal, lumber, farm equipment, and household goods, and they carried out livestock, grain, timber, copper, silver, and other minerals.
Many new towns grew up along the tracks, and communities far from a rail line often stayed smaller because they still had to rely on wagons, stages, or boats.
Railroads also changed the land by encouraging farming on the plains, supporting logging in the forests, and concentrating industry in places like Butte, Anaconda, and Great Falls.
Railroads in Montana Today
Today, railroads in Montana mainly carry freight such as grain, coal, oil, wood products, and manufactured goods, while most everyday passenger travel uses cars, buses, or airplanes.
Some older main lines, like parts of the Northern Pacific route, are now operated by regional companies such as Montana Rail Link, while the national passenger service Amtrak uses the former Great Northern route across northern Montana.
Even though trains are less visible to many people than they were 100 years ago, railroads still help connect Montana to the rest of the country and to world markets.
Key Ideas to Remember
- Early travel in Montana relied on rivers, trails, and wagons before railroads were built.
- The Utah and Northern was the first railroad into Montana and reached the Butte area in December 1881.
- The Northern Pacific and later the Great Northern and Milwaukee Road built major lines across the state.
- Railroads helped Montana grow by supporting mining, ranching, logging, and farming and by bringing in settlers and supplies.
- Today, trains in Montana mostly carry freight, but they remain an important part of the state?s transportation system.
