We have visited theNapa Valleynumerous times, and on almost every trip, we have watched the vintageNapa Valley Wine Traincruise past along tracks that roughly parallel Highway 29. Composed of restored 100-year-old Pullman rail cars once used as first-class coaches by the Northern Pacific Railway, the train runs for 36 miles from downtown Napa to St. Helena and is now pulled by restored 1950s-era locomotives. The tracks were originally laid in 1864 by Samuel Brannan, one of San Francisco’s first millionaires, with the aim of bringing people to his spas in Calistoga.
