Muskingum Electric in Ohio - PV's

Anybody remember the Muskingum Electric system, which until recently hauled coal behind (2) GE E50C's? They also had two PV's, Dover Port and Oak Lane. Any idea what happened to these two heavyweights? Both were white with black lettering for MERR.

I think both are still located at the Hocking Valley senic railway in nelsonville
