I have a dummy Santa Fe SD40 Atlas loco and a powered Chicago Great Western SD40 Atlas loco and would like to take tha inner workings from the powered one and switch them to the dummy unit and visa versa. At first I thought it might be an easy project but as I looked further into this undertaking it appears that it would be more complex than what I figured. Can anyone tell me just what I will have to do? My initial observance when looking at both locomotives tells me that the total innards of both locomotives will have to be removed and that a simple job of just transfering the upper body shell from one locomotive to the other is not an option because the paint on both locomotives would not match. Does anyone have any experience with what I would like to do? Thanks for any help.
Jim
