Quite honestly I hope Anthony was able to get his engine sounds in there. Those are great sounds. Yes, the RPMs are rather high when HEP is turned on, but when turned off, it's rather quiet.
The P42DC's GE 7FDL prime mover spins at 900 rpm (notch 4 or so) when supplying HEP. When not supplying HEP, the prime mover is free to operate within it's design range of ~200 rpm to 1047 rpm. Not sure if this is possible within the game engine at the moment, but in order to simulate this properly, you would need two tractive effort files (one for non-HEP mode, and one for HEP mode), since the power output to the traction motors differs between the modes. Maximum HP to the motors when the prime mover is spinning freely at 1047 rpm is 3850 hp. While locked at 900 rpm, max hp to the motors is 3550 (with no HEP being siphoned off). This HEP difference creates different traction characteristics. But to be honest, if they were just able to give the P42DC a feature that just locked the prime mover at 900 rpm (don't even have to create different traction characteristics) like they did with the EMD F59PHi when they gave it a separate HEP engine that you could activate by pressing "m," it would be a great step up from the original release.
