First of all thank you, this is an excellent model, I use it all the time since I am a huge Milwaukee Road fan. I used drive to Milwaukee all the time in the 70's to watch the Beerline in operation. I also wanted drop the idea in case you ever get bored and maybe looking for a project of doing a SD10, the Milwaukee Road ran them all the time since they preferred the 6 wheel axle trucks over the 4 wheel trucks since they caused less track maintenance . It had the same roof in takes like the GP20 plus it's one of the diesels they put the Hiawatha logo on the nose.

Nope. SD units are 6 axles, GPs are 4 axles.

aren't gp9's are sd9's?
