The Albany-Hudson electric line was a thirty-seven-mile electrified interurban railroad that connected Albany and Hudson from 1900 to 1929, carrying passengers and freight through a network of depots that served as busy centers of community life. Using electricity for high-speed travel between cities and villages separated by rural areas, the line helped spur economic growth in the communities it served. The company generated electricity at Stuyvesant Falls and operated Electric Park at Kinderhook Lake. The line remained successful through World War I, but after the war automobiles and bus lines gradually cut into profits, and the last train ran on December 22, 1929. Trolley cars stopped hourly at East Greenbush, East Schodack, Nassau, North Chatham, Electric Park, Niverville, Valatie, Kinderhook, Stuyvesant Falls, Rossman Crossing, Stockport Centre, Empire, and Stottville, and over nearly thirty years millions of commuters, shoppers, and excursionists passed through the depots for mail, packages, and news. Passenger depots featured overhanging roofs, platform doors opening to waiting rooms and freight storage, and bay windows that gave agents a clear view of the tracks. Surviving depots remain at East Greenbush, North Chatham, Valatie, and Kinderhook, along with a flag-stop shelter at North Chatham, all now private property.
