    @@TemplarKnight1177 It all comes down to wheel control. You can only control the power input into a DC motor so the motor will speed up if the traction is broken and thus it acts like a drag car peeling out. An A/C motor can be speed controlled so that you can dynamically adjust RPM along with power to keep the wheels from breaking traction. It's a dance that has a feedback loop to tell the unit when the wheels are slipping. This feedback and dynamic control allows the motors to push the traction all the way up to the maximum limit allowed by the friction between the track and wheels. They are far more common now than back in the day mostly due to high power semiconductors allowing for extremely high power inverters (the units provided the variable frequency A/C to the motors). DC is more robust in terms of overload but the engineer must manually ride the throttle to prevent wheel slip whereas the A/C units can do it automatically.

    SD70ACe clocks the dynomometer at about 4,500 hp. Others like the SD70MAC at the tail end of the train generate about 4,000 hp. I think that lone GE unit up front puts out about 4,400 hp. I suspect (but don't know for sure) that even the 4,000 hp SD70MAC generates more tractive effort than the GE C44-9W. Yeah, I'm biased toward EMD and have been since I was a kid. I'm 69yo now.

    Starting from a stop on a very steep hill with a very long and heavy train, plus the front engines were not connected at the time as a coupler broke part way between these middle helper engines and the front engines. You could hear all the locomotives wheels slipping even when they were dumping sand onto the tracks for extra traction.

    @ floodedcar 123. That is "wheel creep" - the wheels are just on the verge of slipping and are at maximum adhesion. The sophisticated wheelslip equipment on modern locos allows this condition for maximum pulling power. The wheels are actually turning just slightly faster than if they were not slipping - hence the squeal. You will hear it on all EMD "Super Series" locos too when starting at full load.

    Or...was that a reference to the constant blast of air from near the front of locomotive 4311? Because it annoyed me. Reasonably sure it was from a safety valve on the loco allowing air to escape because the compressor governor is not working properly.
