I believe there are only 11 or 12 C425's out there that are not owned by GVT.
Lake State Railway: 4: ex. PRR all rebuilt with 2000hp prime movers.
LA&L/WNY&P: 3: ex. SP&S(2), ex. NH(1).
NY&LE: 2: ex. PRR(parts), ex. N&W(os).
And 2 or 3 in Arizona (can't remember the name of the mine) ex. N&W(ordered by Wabash). Photo's and news on these engines are hard to find so this may have changed.
