Reply to "Engine won't respond to transformer"

Another factor that comes into play is that in conventional operation (transformer control using varying voltage and DC offsets) is the power MUST go to true 0V on the track. If you are using the direction button or lowering the handle, sometimes the transformer does not go to true 0V output OR you are not doing it long enough for the engine to interpret it as a command VS an intermittent power drop such as seen when the engine is rolling down the track and just drops power for a fraction of time.
