Twists, Turns, and Wet Rails Housatonic RR's NX12 make a rare Sunday Appearance south of Canaan as they return back north from New Milford. Due to heavy track work on the North End, Sunday's NX12 had to make a trip south instead of their normal northbound trip to Pittsfield. The 22 is in the lead of NX12 as it rolls through the curves of the Housatonic River Valley in Kent, CT.
