CELEBRATING NORTH AMERICA'S STEAM RAILWAYS explores the impact the steam engine had on North America by visiting 17 of the continent's most historic and scenic tourist steam railroads. This special takes viewers from the frozen tundra of Alaska to the vast high desert of Arizona, and from the rolling hills of New Hampshire and the Black Hills of South Dakota to the prairies and vast mountain ranges of Canada. The program also visits Steamtown National Historic Site, provides a first-hand lesson on how a steam engine works, and shows why millions of people each year are drawn to visit and ride steam railways.
