Supposedly the 8.5 program is dead in the water, and only those units finished or under rebuild will be done. I think NS as a whole may be done with serious mods to ANY high horsepower DC locos. The SD60E program is on pause so they can crank out the SD70ACUs and I wouldn't be shocked if that program comes to an end too. Meanwhile, GE and Roanoke are doing the Dash-9 AC conversions.
