The Albany-Hudson Electric Trail follows the route of a thirty-seven-mile electrified interurban rail line that connected Albany and Hudson from 1900 to 1929 and used a range of buildings for passenger and freight traffic. The line helped drive economic growth in the communities it served, generated electricity at Stuyvesant Falls, and operated its own amusement park, Electric Park, at Kinderhook Lake. It remained successful through World War I, but after the war automobiles and bus lines 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. These depots were busy community centers where people received mail, packages, and news, and their design typically included overhanging roofs, platform doors opening into 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.
