My grandfather mentioned that they had these on trains. So to control the Speed the driver would move a control-rod to the appropriate resistor needed to go at a particular speed.

If you have an alternator that spins, it's voltage will increase as rpm increases and if you went too fast obviously you would blow your globes.

I've never seen one but I'd be guessing some type of centrifugal switch to push to a higher resistor to limit current and voltage.

Yes, it's all solid state vregs now.
