Since there is nothing inside the body of these slugs except weight the only thing you would have to have would be the dynamic break fan and resistor grids AND the air-intake grills; buried somewhere in that body is some sort of a fan to provide air for those traction motors. The photo of a GP35 slug on page 300 of Kalmbach’s The Contemporary Diesel Spotter’s Guide (Milwaukee, 1989) by Marre and Pinkepank shows unit 2200 looking like someone gave it a Marine Corps hairdo!
I did a search of the all-time index and could find nothing about GP30 Road slugs; if there was a conversion article it probably dealt with a different locomotive.
Would anyone have done this to a rs-2,3,4,5. If so would any of you guys have any pics of this. For that matter someone on here just recently had pics of a remote controlled deisel in a yard. I have a couple rs-2 that have no fuel tank with them do you think it would be cool to have a remote controlled rs on the ol layout. Now I am freelance so prototypical is not realllllly a concern for me.
