They are listed as SD40-2 models, yet lack the porches and HTC trucks that I associate with the SD40-2 series. Are these 6300 series units rebuilt older SD40's upgraded to -2 specs? The sure look like a straight 40, looking at the trucks and lack of front and rear porches. Mike

They could be SD40's that were upgraded with -2 electronics. A number of SD40's have been upgraded to both -2 and -3's/

They 6300 series are Dash 2 rebuilds of SD40's originally ordered by Union Pacific, Chicago & Northwestern, Southern Pacific, and Kansas City Southern.
