The Hoosac Tunnel is a 4.75-mile-long (7.64 km) railroad tunnel through the Hoosac Mountains. Built 1851-1875 to link Massachusetts to Albany, NY, it cost 195 workers their lives. At the Visitor's Museum exhibits depict the effect of the tunnel. Children and adults can experiment with a vintage floor scale that was used for weighing loads up to half a ton. A 30-minute documentary provides a concise, yet detailed, history of the Hoosac Tunnel. The facilities are also used for concerts, lectures, freight yard walking tours and gallery for temporary exhibits. Allow approximately one hour to view the exhibits. Universally accessible.
