SD70ACU
Rebuilds - NS 7326 undergoing
rebuilding
NS 7326 was undergoing rebuilding
in the Smith Shop
This unit is well along in the
process and will soon move to be prepared for repainting. The new
electric
parking brake unit can be seen mounted in its new location on the left
side of the long hood carbody.
Beginning with the 35th SD70ACU
rebuild (7259), NS began adding additional steel to the frame to raise
the maximum weight from 420,000 to 432,000 pounds when fully loaded with supplies (oil water, sand, fuel).
The additional weight allows for better wheel-to-rail adhesion and
reduces wheel slip. The additional steel
is added between the frame rails at each end of the locomotive. In
the photo below, the fresh grind marks
on the rear pilot above the coupler are where the pilot was cut open to allow
for installing the additional
weight. In the front, the deck plate under where the cab sits is cut
open, the weight added, and a new plate is
welded in place. NS will add the additional weight to the first 34 SD70ACU
rebuilds as shop time allows.
