"Jim Crow Car" on Trains(start date: 1902 - end date: 1902)
In 1902, Mrs. Lulu Thurman won her lawsuit against Southern Railroad in the Lexington, KY courts. She had originally asked for $10,000 in damages because the train conductor had thought Mrs. Thurman was a Negro and had forced her to ride in the Jim Crow car. Mrs. Thurman was able to prove to the courts that she was white, and the jury awarded her $4,000.

The Jim Crow railroad car laws would be enacted in 1909, though Thurman's case clearly shows that the segregation of entire railroad cars was in place years before the legislative enactments.
