If you’ve ever driven through North Georgia or wandered around downtown Atlanta, you’ve crossed the Western & Atlantic Railroad. You probably didn’t even realize it. Most people think of railroads as dusty relics of a bygone era or annoying obstacles at a crossing when they're late for work. But the W&A isn't just some old track. It's the reason Atlanta exists. Seriously. No W&A, no "Terminus," no Peach State capital as we know it today.
Steel and steam. That was the internet of the 1830s.
Georgia’s state legislature authorized the Western & Atlantic Railroad on December 21, 1836. They wanted a link. Specifically, they wanted to connect the Chattahoochee River to the Tennessee River. They weren't trying to build a city; they were trying to move goods. The engineers literally drove a stake into the ground in what is now Five Points to mark the "Terminus." It was a muddy, empty spot. But that stake was the heartbeat of a future empire.
The Great Locomotive Chase: More Than a Movie Plot
You can't talk about the Western & Atlantic Railroad without mentioning April 12, 1862. It’s the stuff of legends. James J. Andrews, a Union spy, led a band of raiders to Big Shanty (now Kennesaw). They stole a locomotive called The General. Their plan? To rip up the W&A tracks, burn bridges, and cut off the Confederate supply line to Chattanooga.
It was bold. It was also kind of a disaster.
William Fuller, the conductor of the train, didn't just give up. He chased them. On foot. Then by handcar. Then by commandeering three different locomotives, eventually ending up on The Texas, which he ran in reverse at breakneck speeds. The chase covered 87 miles of W&A track. It ended just north of Ringgold because The General ran out of fuel. Most of the raiders were caught. Many received the first Medals of Honor ever awarded.
If you visit the Southern Museum of Civil War and Locomotive History in Kennesaw, you can see The General sitting right there. It looks smaller in person than you’d expect for something that caused such a massive historical ripple.

The Engineering Nightmare of Tunnel Hill
Building a railroad in the 1840s wasn't exactly a walk in the park. The geography of North Georgia is basically one giant obstacle course of ridges and valleys. The biggest headache was Chetoogeta Mountain.
Engineers realized they couldn't go over it. They had to go through it.
The Tunnel Hill project was a brutal undertaking. It took two years. Workers used black powder and hand drills to chew through 1,477 feet of solid rock. When it opened in 1850, it was the first major tunnel in the South. It was a bottleneck, sure, but it was a functional one.
Interestingly, the original tunnel eventually became too small for modern, larger rail cars. In the 1920s, they built a new one right next to it. Today, you can actually walk through the 1850 tunnel. It’s damp. It’s dark. It smells like old stone and history. You can still see the drill marks in the walls. It makes you realize how much sweat went into every mile of the Western & Atlantic Railroad.
Who Actually Owns the W&A?
Here is a weird fact that catches people off guard: The State of Georgia still owns the Western & Atlantic Railroad.
Wait, what?

Yep. While almost every other major rail line was sold off to private corporations like CSX or Norfolk Southern decades ago, Georgia held onto this one. It’s officially the only railroad in the United States that is owned by a state government but operated by a private entity under a long-term lease.
Currently, CSX Transportation leases the line. They pay millions of dollars into the state treasury every year for the privilege. The tracks run from Atlanta to Chattanooga, covering about 138 miles. It’s a cash cow that has been funding Georgia’s infrastructure and education in various ways for over 150 years.
The Dark Side: Convict Lease and the W&A
We have to be honest about the history here. It’s not all heroic chases and engineering marvels. After the Civil War, the W&A was at the center of the "Convict Lease" system. This was a brutal practice where the state "leased" prisoners—mostly Black men—to private companies to work on the railroads.
The conditions were horrific. Essentially, it was slavery by another name. The men worked in the coal mines and on the tracks under the threat of the lash. The Western & Atlantic was a primary beneficiary of this forced labor during the late 19th century. Historians like Douglas Blackmon have documented how this system helped rebuild the South’s economy at a staggering human cost. You can’t tell the story of the W&A without acknowledging that the tracks were often laid and maintained by men who had no choice and no pay.
Why the Route Never Changed
If you look at a map of the Western & Atlantic Railroad from 1860 and compare it to a modern satellite view, they are nearly identical.

Physics. Trains don't like hills. The original surveyors—guys like Stephen Harriman Long—found the path of least resistance through the Appalachian foothills. They followed the valleys. They hugged the rivers. Even with modern technology, those original grades are still the most efficient way to move heavy freight from the Tennessee Valley to the Atlantic coast.
The "Zero Mile Post," which marked the end of the W&A in Atlanta, is still a point of pilgrimage for history nerds. It used to be under a bridge in a gritty part of downtown. Now, it's been moved to the Atlanta History Center for preservation. It’s just a simple stone post. But it represents the birth of a metropolis.
Visiting the W&A Today
If you want to actually see this history, don't just look at a map. Get out there.
Start in Kennesaw at the Southern Museum. Then, drive up to Tunnel Hill. The historic site there is fantastic and haunting. You can stand in the middle of the old tunnel and feel the cold air pushing through from the other side.
Next, head to Marietta. The tracks run right through the middle of the square. You can sit at a sidewalk cafe, drink a coffee, and watch a mile-long CSX freight train rumble past on the exact same alignment that Fuller and Andrews fought over in 1862. It’s visceral. The ground shakes. The horn blares. It’s a living museum.
Finally, check out the Chickamauga and Chattanooga National Military Park. The railroad was the strategic prize of the entire Atlanta Campaign during the Civil War. Sherman knew that if he could hold the W&A, he could feed his army. If he lost it, he was finished. Every bridge and every culvert on this line was a potential battleground.
Practical Steps for Your Trip
- Check the Museum Hours: The Tunnel Hill Heritage Center has specific hours and guided tours are usually the only way to get inside the tunnel safely.
- Walk the Beltline: In Atlanta, parts of the old rail corridors that connected to the W&A are now the Beltline. It gives you a sense of the scale of the rail hubs.
- Download a Rail Map: Use an app like OpenRailwayMap to see how the W&A (now the CSX W&A Subdivision) weaves through modern neighborhoods.
- Respect the Tracks: Remember, this is a "hot" line. CSX runs dozens of trains a day. Stay off the active tracks and take your photos from a safe distance.
The Western & Atlantic Railroad isn't a museum piece. It’s an active, vibrating artery of the American economy that just happens to be wrapped in 180 years of grit, war, and political maneuvering. It’s arguably the most important 138 miles of dirt in the South. Next time you're stuck at a crossing in Acworth or Dalton, look at the rails. You aren't just waiting for a train; you're looking at the spine of Georgia.
Actionable Insight:
To truly understand the impact of the W&A, visit the Southern Museum in Kennesaw first to see The General, then drive the 40 minutes north to the Tunnel Hill Heritage Center. Walking through the 1850 tunnel provides the physical context of the labor required to build this line that static museum exhibits simply cannot replicate. For those interested in the state's role, the Georgia Department of Transportation (GDOT) maintains public records of the current lease agreements, which offer a fascinating look at how a 19th-century asset still generates millions for modern taxpayers.
