From their FB feed:
ScaleTrains.com : if the DASH-9 sells well in N scale, we plan to offer the AC44C6M in N as well as HO. Shane
(these are the ac4400cw-ish rebuilds of NS spartan cab C40-9's...)
I'm all in once they at least offer a Dash-9 (W or Spartan Cab) in the original NS paint scheme (instead of the Horse head) I have enough of horse head schemes in later GE variants (Gevos, Teir4) I'm not sure why they didn't start out with that scheme as so many Dash-9's still on the rails yet to be re-painted. hence why I'm waiting.
