Galena and Chicago Union Railroad Begins Operations

On September 12, 1846, the Galena and Chicago Union Railroad inaugurated service from Chicago to Oak Park, Illinois, marking the birth of railroading in the Windy City. Powered by the locomotive Pioneer, a 4-4-0 built by Baldwin, the line initially hauled lumber and grain. This modest 8-mile route overcame swampy terrain using innovative corduroy roads and wooden trestles. Key figure William B. Ogden, Chicago's first mayor, championed the project to connect the growing metropolis to western markets. The opening foreshadowed Chicago's rise as America's rail hub, eventually linking to the transcontinental network. Lasting impact includes spurring industrial growth and establishing standards for Midwestern rail expansion during the antebellum era.
