I just have a hard time believing any engine (no cars) will go that fast in level 1, or notch 1, or 13 percent throttle in real life. (it's not just 1 engine (sd-40) but almost any engine I drive.
Wouldn't friction keep the speed down to a more manageable notch 1 speed? The only thing more cars do is slow down how fast it reaches that speed.
And if it's true how do I find engines that don't have such a high end speed?
I know this is NOT accurate but the observations of someone who is blowing off steam
