What makes a Super 7 super? What is so great (or ungreat) about them?

Simple marketing.

I believe Super 7 locomotives are hulks of dash 7 locomotives rebuilt by GE to dash 8 standards with many dash 8 components. Also, the units were not necessarily rebuilt in kind, i.e., a B-30-7 could become a Super 7 B-23. By the way, the crews on the Monongahela really liked their Super 7 B-23s.

Actually… to my knowledge, NO Dash-7 locomotives were ever converted to Super-7s. The base for the Super-7s has been old U-series locomotives. The Monongahela’s Super-7s started out as U23Bs from various lineages.

They are "almost dash-8" rebuilds, but not quite. Consider them Dash-7.5's.

Obviously they are also built from EMD parts, too. Look at those Blomberg trucks.

The reason for the Blomberg trucks is that the original U23B was built with them from trade-in EMD locomotives. For examples… C&O had an entire group of U23Bs built with EMD Blomberg trade-in trucks.

They are really nice little units. It is easy to see why the Mon crews would like them.

There was one assigned to the Sandusky local for a while, but it was in Belletucky the other day.

The Monongahela Super 7's were all ex Western Pacific U23B's like the GE demo Super 7's were. Other Super 7's for Canada were ex ATSF and MP U23B's, IIRC.
