First Great Britain, then Old Europe were discovered by Michael Portillo across several seasons of fascinating TV, all with the help of train fanatic George Bradshaw, and the wonderful guide books he wrote over a century ago. Michael now undertakes an epic trip from New York and Boston on the American East coast right down to the Deep South of Atlanta and New Orleans, and then on to Chicago, Colorado, New Mexico, and ultimately finishing in San Francisco. 'Great American Railway Journeys' continues Portillo's involving blend of social history cum travelogue in the New World.
