"Might Mouse", a Whiting 2 TM trackmobile, makes its first freight move on the Shelburne Falls and Colrain Street Railway trackage at the Shelburne Falls Trolley Musuem in Massachusetts. "Mighty Mouse" recently came out of three years of mothballs after serving a dam project in the south central United States moving flatcars with cement mixers on them. The Whiting 2 TM is about forty years old and is on lease to the museum to move equipement and occaisional inbound interchange from nearby Guilford Rail System.
