I just purchased a Iowa northern CF7. I am very pleased with this locomotive as it is a small branch line that travels through a short section of northeast Iowa. I think it is pretty cool of Athearn to make this locomotive, since the RR is very small. I see these locomotives daily as they travel through a town I'm a policeman in. It runs like an athearn, it has the typical growl, but to me this is a collectors item. Check them out the bright yellow scheme is not hard to miss.
