On the trail of one of America's most famous railroad names, Michael heads south to Pullman to investigate the legacy of its founder, George Pullman. Beside the Kankakee River, Michael is invited to visit the Frank Lloyd Wright-designed house that changed the face of American architecture. On the platform at Kankakee station, Michael parties with the locals as they celebrate the City of New Orleans rail service, immortalised in song by Arlo Guthrie. He gets his hands on a vintage hooter riding on the Monticello Heritage rail line and in Champaign learns a thing or two at a railroad university.
