Regarding the SD90s that were on the MM&A, which one of the three are these engines; the SD9043MAC, a 4,300 HP locomotive with the 265H engine; 6,000 HP SD90; or the SD90MAC-H II.
If these have the 6,000HP locomotives, could they be converted to 4,300 HP engines? Are the frames, electronics and trucks of question in addition to the engines themselves?
