The Story
Formed in 1846 and named for the prominent citizen John Blair, this county sits in the Allegheny highlands with Hollidaysburg as its seat. Its fortunes were transformed by the coming of the railroad: the city of Altoona, founded in 1849, grew into one of the great railroad centers of America. There the Pennsylvania Railroad built vast shops that employed generations of workers.
Why it matters
Altoona embodies how the railroad remade the American landscape, turning a mountain outpost into a hub of the nation's most powerful transportation network.
The story behind this marker
AI contextThe era
Blair County was born in the winter of 1846, carved out of two older neighbors in the rugged high country where the ridges of central Pennsylvania begin to pile up into the Alleghenies. This was the Early Republic still finding its shape — a young, restless nation pushing westward, and Pennsylvania was one of the busiest corridors of that push. The mountains here had long been a wall between the settled east and the Ohio country beyond, and every generation asked the same question: how do you get people and goods over them?
The answer, in this county's case, would be iron rails. When the settlement was first organized, Hollidaysburg was already a working town of some size, incorporated a decade earlier as the local seat of government. It sat at a natural gateway in the mountains, the kind of spot where routes converge and commerce collects.
Then came the railroad age, and everything accelerated. By the second half of the nineteenth century — the era of Reconstruction and the Gilded Age — the county had become something its founders could scarcely have pictured: a place defined not by farms or forts but by locomotives, machine shops, and the roar of industry echoing off the hills.
People & events
The county carries the name of John Blair, remembered here as a prominent citizen of the region who died in 1832, more than a decade before the county that honors him was formally established. Naming a new county for a respected local figure was a common courtesy of the age — a way of stitching a community's memory into the map itself.
But the story that truly shaped this place is the story of a city that did not yet exist when John Blair was alive. Altoona was founded in 1849, deliberately laid out as a railroad town, and it grew with astonishing speed into one of the great railroad centers of the country.
Where the county seat of Hollidaysburg represented the older order of things, Altoona represented the new. Vast shops rose to build and repair locomotives and cars, and generation after generation of families found their livelihoods tied to the rhythm of the rails. The county's identity became bound up with the men and women who kept America's trains running.
Its place in the American story
To understand Altoona is to understand how the railroad remade the United States. In a single lifetime, rail transformed the country from a collection of isolated regions into a connected continental nation — and towns built expressly to serve the railroad, like Altoona, were the beating heart of that transformation.
The shops here were part of one of the most powerful transportation enterprises the nation ever produced. The work done in such places — building the engines, forging the parts, maintaining the endless machinery of movement — was the unglamorous foundation on which the whole industrial economy rode.
So this mountain county stands as a compact lesson in a national truth: the railroad did not just cross the American landscape, it created new communities out of nothing, drew workers from far away, and turned quiet highland outposts into engines of the modern economy.
If you visit
Come to Hollidaysburg for the older layer of the story — a county seat with the settled, dignified feel of a town that has been the center of local life for nearly two centuries. Walk its streets and you're walking the part of the county that predates the railroad boom.
Then let the landscape itself tell you why the railroad mattered so much. Look at the mountains rising all around you and imagine engineers staring at that same wall, trying to figure out how to get a train over it. The terrain is the whole reason this place became what it did.
This is a natural stop for anyone tracing the great arc of American railroading through the Alleghenies. Give yourself time to feel the contrast between the quiet county seat and the industrial city that grew up beside it — two chapters of the same mountain community, written a generation apart.

Canal Basin
Hollidaysburg, PA · est. 1982
At Hollidaysburg, the 127-mile Juniata Division of the Pennsylvania Canal met the Allegheny Portage Railroad, an ingenious system that hauled canal boats over the mountains toward Johnstown, 36 miles west. The canal opened in 1832 and the railroad in 1834, together forming a continuous route across the formidable Allegheny barrier. Engineers marveled at the portage line, which climbed nearly 1,400 feet in just ten miles using inclined planes.
Altoona
Altoona, PA · est. 1947
Altoona was born of the railroad, laid out in 1849 as the mountain-base terminal from which the Pennsylvania Railroad pushed its tracks westward over the daunting Allegheny front. Within a generation the town's yards and shops made it one of the great railroading centers of the nation. In 1867 it hosted a War Governors' Conference, one of several wartime and postwar gatherings that made the city a meeting ground for state leaders.
Pennsylvania Railroad Shops
Altoona, PA · est. 1996
In 1850 the Pennsylvania Railroad laid its first track to Altoona and built its first repair shops there, and the town grew up around the industry. Nestled at the foot of the Allegheny grade, Altoona became the beating mechanical heart of the mightiest railroad in America. By 1925 it held the nation's largest concentration of railroad shops, where some 16,500 workers built and mended the locomotives and cars that moved the country.
Railroad Shopmen's Strike of 1922
Altoona, PA · est. 2010
When American railroads moved in 1922 to roll back the wage and workplace gains that shop workers had won during World War I, more than 300,000 skilled tradesmen walked off the job in one of the largest strikes in the nation's history. The powerful Pennsylvania Railroad, whose sprawling shops in Altoona were among the largest in the world, led the industry's fierce resistance. Though the strike was broken, the bitter conflict pushed Congress toward the 1926 Railway Labor Act, which affirmed workers' right to organize.
