Monongahela Connecting

Looking for pictures of Monongahela Connecting
Alco S2 #158 preferably in its as delivered
scheme but later views as well. Will purchase
negs or slides but a good hi-res scan may
be ok too. All types of pix: roster, action,
whatever.

As this is a less than well know road, please
pass this search along to others.

Thank you!
