by GN 599
The SD-9. The BNSF 6126 is my favorite ex- GN 599. They were all long hood forward. The GN ordered the 598 and 599 with dyno's specificly for the OC&E because of the 2.0% grade. They took turns with the SP operating it until 1975 when Weyerhaeuser bought the whole thing. All of the other GN SD-9's and SD-7's didnt have dynos and alot of folks dont know of the 598 and 599. I didnt think you could break em loose with 1750 horsepower but the 6126 made a believer out of me. They are both laid up good order. Under remarks for the 6126 it says ''unit is not fuel efficient''. I guess with a build date of 5-58 it is an efficient unit nonetheless.
