Norfolk Southern has many awesome and unique locomotives that I am sure Dovetail can capitalize on big time if they were to make and offer them. Some examples are the SD70ACC, SD70ACu, AC44C6M, SD60E, SD40E, and the GP and SD -ECO units. NS has a great locomotive rebuilding program based at the shops in Juniata. In addition, NS as like 20 or something heritage units for the SD70ACe and ES44AC, which I believe would also be extremely popular. I'm sure the modders are already working on creating heritage units.
Ditto on all of these. We should also get a Roadrailer consist and some other NS modern rolling stock.
