If the engine and axle are direct connected how is the speed and power of the car controlled?
By a throttle lever which controls the now of steam. This little lever does it all, and is so small in size and easy to handle that it is placed right on the steering post under the wheel. To get more speed or more power it is only necessary to advance the lever. This opens the throttle valve in the steam line and lets more steam to the engine. The steam is controlled like the water in a faucet, in fact, the functions of faucet and throttle are identical.
