BNSF 3630 and 3631 hang around at Murray Yard in Kansas City, MO on Tuesday, July 8th, 2025. BNSF erroneously defines these "Heavies" as ET44ACH, when it should be ET44AH. Photo credit: Trainspo user Maersk.146

Notes
(1) Could also be ordered with GE's Steerable truck.
(2) Ballasting to 432,000lbs creates an ET44AH, which has an adhesion factor of 47.4%. Another value I've found is 46.8%.
(3) 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. This is done by typing "*3" (without quotes) after the number value when editing the locomotive config in the E2 editor. TM values shown are for a GE B22 which is similar to the B132Bs found on these locomotives.
