operate!
What are the circumstances under which people have had motor cutouts operate?
Is it through crawling with a heavy train US-style, or perhaps using PWM
control (generates more heat in coils)?

I’ve had one motor where the cutout failed. After removal it worked fine. I now
remove all of these on my DCC conversions. And rely on the overload protection
on the decoder.
I was also experimenting with swapping the can motor from a dead motor. This
motor had more high end speed, but ran at about 1 amp! The cutout would shut the
motor down after about 60 seconds of running. Idealy a replacemnt motor would
have lower speed and greater torque.
