Steam locomotives

Chronicles history's greatest locomotives, including Southern Pacific's cab-forward articulateds that conquered California's formidable Donner Pass; Boston & Albany's Berkshires, the first Lima Superpower; Pennsylvania's ill-fated Duplexes, built to compete with new diesels and operated at sustained speeds faster than 100 miles per hour; and Northern Pacific's gargantuan Yellowstones, locomotives so large that a banquet for 12 was once held in one of their fireboxes.
