They are quite active, running and maintaining the line from Rt. 16 at the Miss Wakefield Diner toward Wolfeboro, at the Fernald engine house at Rt. 109, which is a mile or two short of downtown Wolfeboro. The station at downtown is a visitor center. They are a great group.

There are some links on the web site with the history of the line. I think the railroad last operated around 1985. the steam engine that was there is, last I heard, at Edaville on display. I am not sure if that is still the case
I had posted some photos on NERAIL from the 1970s at the Sanbornville connection, which was the link to the main line. The link has long since been severed. The turntable pit is still there in Sanbornville.
