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. (...) (25 years ago, 2-Nov-99, to lugnet.off-topic.geek, lugnet.trains)

Great detailed explanations! If I simplify things, the throttle on a steam engine controls Torque. To set a certain speed with a certain load, a certain torque is needed. The speed regulator (governor) is a device that controls the applied torque so (...) (25 years ago, 29-Oct-99, to lugnet.off-topic.geek, lugnet.trains)

(...) Sorry Larry, not true. The throttle controls the pressure in the steam chest (Ideally), which controls the speed.
