Wilton Historical Society’s Great Trains show is currently underway at 224 Danbury Road. The train show encompasses four rooms in the historical Society, and features interactive buttons, switches, and even a train with a camera on its smokestack. Many Wilton volunteers donated their time and model railroad supplies to make the show quite the spectacle, including former First Selectman Bob Russell. Great Trains is open until Jan. 20, and is free for children under 12. Admission for nonmembers is $10.
