The SD 7/9 a few years ago from Sunset. Great Northern did not use dynamic braking, there were cold weather covers/hatches for some of the fans. The couple of Sunset models, I have, tend to be proto-typical. They did the SD9 in several different roads also. Probably why, they are offering GP7/9, they have molds, and are changing the trucks/drive system. A low investment project. IMO. Mike CT. E-mail Sunset, or call. Your input/money, , is important to them.
