SPS CSX GP30 Power Fix

For what it's worth, the developer documentation is incorrect about the measurements used for MaxPower as the game uses Horsepower instead of kilowatts. Searchlight content along with content from most other developers also use horsepower and blueprint editor also refers to it as horsepower. Ancedotally i can say testing up grades at various loads has confirmed this

I don't think there's anything wrong with the GP30.

And don't confuse SI units, there's a difference between power and force .

Power is determined via Force * distance / time

Also, this is a highly scripted loco, so if you're not sure how the script modifies the values to have a realistic outcome, which I'm sure these devs have thouroughly implemented, you can't judge the loco by the simulation blueprint alone.

Without any scripts, these values are simply used and applied in relation to the "Regulator" ControlValue among other factors, which is the case for old Kuju stock using the core engine only. But not for scripted locos, where the Regulator is controlled via a VirtualThrottle processed by a script, and also the physical stuff (see Armstrong Powerhouse tweaked grade physics in plain lua).
