For a long lifetime, the railroad was the biggest thing in South Dakota — the industry that built the towns, moved the crops, and employed a small army of workers. If your family lived along a rail line, there is a good chance the railroad is part of their story.

South Dakota’s growth rode the rails. The major lines across the state included the Chicago & North Western and the Milwaukee Road. The railroads opened the eastern wheat frontier and pushed toward the Black Hills gold country.
Railroad towns
Whole towns grew up around the division points, roundhouses, and repair shops — places like Aberdeen, Huron, and Pierre. A railroad job — brakeman, fireman, engineer, section hand, shopman — supported thousands of South Dakota families, and the depot was the center of town life.
The boom era
The great building period ran through the 1870s through the 1900s, when track spread across the state and tied farm and factory to national markets. The railroad decided which towns thrived and which withered, and its coming is written all through the census and land records of the era.
