The trains ran on iron rails, but the most consequential freight they carried was human, and much of it was arranged by Black businessmen moving inside the system itself."]},{"heading":"Freight with a heartbeat","paragraphs":["Stephen Smith and William Whipper, partners in a Columbia lumber yard, owned their own rail cars on the line — legitimate freight by the bill of lading, and by documented tradition a regular forward line for freedom seekers hidden among the cargo. William Goodridge, the mixed-race merchant out of York, worked the same corridor. The route passed within miles of Christiana, where in September 1851 a Maryland slaveholder named Gorsuch was killed trying to take four men back, and thirty-eight people were indicted for treason for refusing to help him. Not one was convicted."]},{"heading":null,"paragraphs":["The line survives as Amtrak's Keystone corridor, still running trains over the old roadbed.
