Berkeley County’s economy has never been static. Since the earliest days of European settlement, its geographic position — at the northern gateway to the Shenandoah Valley, where road, river, and eventually rail converged — made it a hub of commerce and production. The county’s industrial evolution spans nearly three centuries, from frontier mills and iron furnaces to the massive distribution centers and healthcare campuses that define its economic landscape today.
The Flour and Grist Mill Era
Before the railroad age, Berkeley County’s rivers powered its early industry. The Opequon Creek, Tuscarora Creek, and their tributaries provided reliable waterpower for dozens of grist mills, flour mills, and sawmills that supplied the agricultural communities of the Valley. By the early 1800s, Martinsburg was already a prosperous market town, with millers, blacksmiths, tanneries, and distillers forming the backbone of its artisan economy.
The county’s fertile soils made it a premier wheat-growing region, and Martinsburg flour was shipped to markets as far away as Baltimore. The Adam Stephen house, built in 1789 and now a National Historic Landmark, stands as a monument to the prosperity of that agricultural-industrial era.
The Baltimore & Ohio Railroad Shops
No single industrial development transformed Berkeley County more profoundly than the arrival of the Baltimore & Ohio Railroad. When the B&O extended its main line through Martinsburg in 1842, the town became not merely a stop on the route but a major operational hub. The B&O established locomotive repair and maintenance shops in Martinsburg that grew into one of the largest railroad industrial complexes in the antebellum United States.
At their peak, the Martinsburg shops employed hundreds of skilled craftsmen: machinists, boilermakers, blacksmiths, and carpenters who built and repaired the locomotives and rolling stock that moved the nation’s commerce. The shops represented a concentration of technical skill and capital investment unusual for a town of Martinsburg’s size. They also created a politically and economically powerful working class — a class that would make its voice heard in the Great Railroad Strike of 1877.
The Strike of 1877
The Great Railroad Strike of 1877 began in Martinsburg. When the B&O cut wages for the second time in a year, workers walked off the job on July 16, 1877, and refused to let trains move. The strike spread like wildfire across the national rail network, triggering the first major labor uprising in American history. President Rutherford B. Hayes dispatched federal troops — the first time in U.S. history that a president used the military to suppress a labor strike. The confrontation in Martinsburg foreshadowed decades of labor-capital conflict and made Berkeley County a footnote in every serious history of the American labor movement.
Textiles and Manufacturing: The 20th Century
As the railroad’s dominance faded in the early 20th century, Berkeley County adapted. Textile mills, particularly during the 1910s through 1950s, provided significant employment. The county’s relatively low land costs, proximity to rail infrastructure, and available workforce attracted a variety of light manufacturing operations. Clothing manufacturers, furniture makers, and food processing plants set up operations in and around Martinsburg through the mid-20th century.
The post-World War II boom brought new industrial investment. Procter & Gamble established a manufacturing facility in the county. Interbake Foods, later acquired by George Weston Ltd., ran a major cookie and cracker plant. Several defense-related manufacturers were drawn by the proximity to Washington, D.C., and federal contractors.
The Apple Industry
For much of the 19th and early 20th centuries, the apple orchards of Berkeley and Jefferson counties made the Eastern Panhandle one of the most important apple-growing regions on the East Coast. Dozens of orchards — some covering hundreds of acres — produced varieties prized for fresh eating, cider, and commercial processing. Cold storage warehouses and packing operations employed hundreds seasonally, and the annual apple harvest was a defining feature of Berkeley County life. While commercial apple growing declined significantly in the latter half of the 20th century as competition from western states intensified, some orchards persist, and the heritage is preserved in local festivals and historical accounts.
Healthcare as Industry: WVU Medicine Berkeley Medical Center
In the 21st century, healthcare has emerged as one of Berkeley County’s largest employers. WVU Medicine Berkeley Medical Center, the successor institution to the old City Hospital of Martinsburg, anchors a growing healthcare corridor. The medical center employs thousands and draws patients from across the Eastern Panhandle and surrounding tri-state region. Its expansion has catalyzed growth in medical offices, specialty clinics, and related services throughout the county.
The Distribution and Logistics Boom
Perhaps no sector better illustrates Berkeley County’s modern industrial identity than logistics and distribution. The county’s location — roughly equidistant between Baltimore, Washington, D.C., Philadelphia, and Pittsburgh, with direct access to Interstate 81, one of the East Coast’s primary freight corridors — makes it ideal for large-scale distribution operations.
Amazon, Procter & Gamble, Macy’s, Aldi, and numerous other major corporations operate fulfillment and distribution centers in Berkeley County. These facilities collectively employ thousands and have transformed former farmland on the county’s periphery into industrial campuses. The growth of e-commerce has only accelerated this trend: Berkeley County is now one of the most logistics-intensive counties in West Virginia by employment.
Looking Forward
Berkeley County’s industrial base continues to evolve. Efforts to attract advanced manufacturing, technology firms, and renewable energy investment are ongoing. The county’s infrastructure advantages — Interstate 81, the CSX rail mainline (the former B&O line), and proximity to major markets — remain as relevant in the 21st century as they were in the 19th. The challenge for local economic development officials is ensuring that this growth translates into broadly shared prosperity for all Berkeley County residents, not merely those employed in the higher-wage sectors.
From the thundering locomotives of the B&O shops to the automated conveyors of modern fulfillment centers, Berkeley County’s industrial identity has always been shaped by its ability to move goods, serve markets, and adapt to changing economic realities.
