Hi,
The GN had a number of GP35s though (all in simplified and one too in Big Sky Blue paint schemes), which I always thought didn't look THAT much different from the 38s. (

Don't tell anybody I just said that!

) How does Justin Cornell's repaint policy look like? I tried to find out a while ago but didn't get very far, then forgot about it.
Actually, quite a lot of GN's diesel roster can already me modeled in RW, or already exists:
NW2, NW5, RS3, SW1200, SW1500, FT AB, F3 AB, F7 AB, F9 B, E7 A, GP9 (long hood forward), GP30, Alco FA/B -1 and -2
And with a bit of artistic license, these RW models could also become:
RS2, SW7, SW8, SW9, GP9m (FT rebuilds)
Cheers,
Michael
