Among hundreds of thousands who joined Martin Luther King, Jr. for a 1963 march on Washington D.C for civil rights were some 800 Chicagoans who traveled there by train. Chicago writer and now-legend Studs Terkel went with them. He brought his tape recorder and turned the sounds and voices of his fellow travelers into a documentary he called "This Train." The journey culminated in Washington with King's now-famous "I Have a Dream" speech, delivered 45 years ago today. From Studs Terkel's archives, here's the first part of that documentary, as the travelers head toward Washington on the train.
