I've got a Lionel Rock Island 44T unit that I will be turning into an electric - I have a GG-1 pantograph to mount on it and will add some more bits and cover up the end radiator vents. It'll probably end up being painted Milwaukee Road. The RI 44T doesn't have Blomberg truck frames which will help the look.
I just placed the pantograph on top to give an idea of what it'll look like.
