After you have established an address for the throttle, you should be able to run the train on your layout. The Speed Control panel is used to control the speed and direction on your locomotive when the throttle is used to operate on a layout.

The throttle slider controls the speed and indicates the percentage of power from Stop to 100%. Use mouse to drag the slider to the desired speed

Alternately, the slider may be set to STOP in the middle and move to + 100% or to -100% to control locomotive speed.
