Ground Flying is a term coined by Carl Purinton to describe the sensation of operating a live steam locomotive while laying on a flatcar close to the ground. This riding posture lowers the rider's center of gravity, thus stabilizing the rider and allowing much higher speed of operation.
Ground flying was "invented" at Carl's track in Boxford, Mass. and referred specifically to the 3-1/2" gauge equipment.
The "ground flying' was referring to the 3-1/2" gauge track. It was more comfortable to lie down on a long flat car and run your locomotive than to sit upright as the balance was tedious. Because many of us laid down to run, we could go faster. There have been many speed records on that little track! A lot of fun!
October 5, 1974. It was a beautiful day at Carl Purinton's track in Boxford. Dick Symmes & Bob Hornsby were running their 3-1/2" gauge locomotives. Dick took this photo while Bob went roaring by. They found it easier to run with more stability lying down on these small trains, plus they could go faster and be safe.
Charlie Purinton "ground flying" on his father's 3-1/2" gauge Boxford Outer Belt track. According to John Kurdzionak, the loco is a Delaware and Hudson style Wooten-fireboxed engine called "Skeevers". Its history is written about in the Charlie Purinton live steam history book. They tried several different ashpan configurations on it before they got it to steam well. Photo by Bob MacMillan.
