"Mighty Mouse", a 1960's era Whiting 2 TM Trackmobile, makes a big freight move at the SFTM in Shelburne Falls, MA. 2 TM models have been known to move thirteen auto racks on level ground. This unit was mothballed for three years after serving on a dam project shifting flatcars with cement mixers. SFTM tries to recreate it here with their flatcar made from a former steam tender.
