Notes

⚠: Not Verified or Educated Guess

(1) GE lists the GEVO-12's HP for traction at 4365 as of 2016, earlier manuals list it at 4390.

(2) Could also be ordered with a Self-Steering truck, which would supposedly reduce wear on the wheels.

(3) Current listings are an approximation of the AC4400CW's GMG192 alternator. The Evolution series uses the 5GMG206A alternator instead.

(4) AC electrical gear is three-phase. Values shown here is for a single phase; the value used by RLC PT2 should be 3 times the value shown.

(5) The ET44AC uses 5GEB132B traction motors, which are a modified version of the AC4400CW's 5GEB13 traciton motors. Listed ratings are for the GE 5GEB22, which is similar.

(6) GE lists the ET44AC's max engine RPM at 900.
