Michigan Central Railroad Depot

The Michigan Central Railroad ran a freedom corridor between Chicago and Detroit, and Jackson's depot was its most documented escape hatch. The case that made it famous came on January 27, 1847: four Kentuckians broke into the Marshall home of Adam and Sarah Crosswhite — a family that had escaped slavery and settled in Michigan — to drag them back. The town of Marshall rose, blocked the slave catchers, and smuggled the family east to Jackson, where they spent the night hidden in the woodyard of the Michigan Central passenger station.

The next morning George Ingersoll boarded the train at Marshall to make sure the Kentuckians weren't on it; when it reached Jackson he stood on the rear platform — the prearranged signal that it was safe — and the Crosswhites boarded for Detroit and then Canada. That same year John White, escaped from a Kentucky plantation and working a Jackson County farm, was tipped off hours ahead of the armed party coming for him and caught the same eastbound line to Detroit. The trains were faster than horses — the iron horse literally outran the slave catchers, which is why the railroad itself became the Underground Railroad's fastest leg.

The 1873 Italianate union station that replaced the original depots still stands — the oldest continuously operating train station in the United States, still served by Amtrak on the line where the Crosswhites' escape helped push the country toward the Fugitive Slave crisis of the 1850s.

The Jackson depot is the archive's signal file — the station where a man standing on a rear platform told a hidden family the coast was clear, on the railroad that was the fastest Underground Railroad in America.
