Well, James corrected me and he's right(1). The Throttle is a restrictor
(if you look up throttle, one meaning is to cut off airflow) in the
steamline. Restricting the flow reduces the pressure in the steam chest.

However most valve gear (cf. Walschaert and Baker to name two) are
complex linkages that can control both the duration and timing of the
valves inside the steam chest, hence regulating the power another way.

1 - James seems to always catch me in little mistakes. I'd be annoyed by
it if they actually were actual mistakes. As you all know I never make
misteaks, just ask me...

Thanks for the explanation! (Wow, so it is really possible to explain how the steam engine works without using a single picture!) (...) This looks like the PWM (pulse width modulation) method RCX uses to control its motor powers. Why the steam (...) (25 years ago, 2-Nov-99, to lugnet.off-topic.geek, lugnet.trains)
