If anybody of you has seen the drivers cabin of a suburban train or an Electric AC/DC engine of a Locomotive, then you can see the two levers on top of the vertical spindle which the driver rotates to actually dirvwe the train. This is called the Master Control That is used to control the speed and do braking ( one for each).

Any one ha got any idea about how this system actually works and how is it designed to synchronise with the high voltage motors nad the vaacuum braking system usually found in such locos.

Any insight is appreciated.

    would it be an electronic speed control? Thus work by controling and adjusting the electrical flow? many trains now are controlled by a central command center and the driver primarily acts as a safety backup and opening/closing of the doors.

    In the company i work, we have diesel-electric locomotives, and the brakes are of the compressed air type, form wikipedia: <a href="https://en.wikipedia.org/wiki/Railway_air_brake" target="_blank" rel="nofollow noopener noreferrer">Railway Air Brake</a>
    The way to control it is to control the compressor located in the locomotive, what you really do is control a valve wich release the air to the atmosphere like the article explain.
