For a long lifetime, the railroad was the biggest thing in Illinois — 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.

Illinois’s growth rode the rails. The major lines across the state included Illinois Central, the Burlington, the Rock Island, the Santa Fe, and a dozen more. Chicago grew into the greatest railroad hub on earth — every major line in the country reached it.
Railroad towns
Whole towns grew up around the division points, roundhouses, and repair shops — places like Chicago, Galesburg, Decatur, and East St. Louis. A railroad job — brakeman, fireman, engineer, section hand, shopman — supported thousands of Illinois families, and the depot was the center of town life.
The boom era
The great building period ran through the 1850s through the 1880s, 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.
