The reversing board that is in the Williams tender with sound. How do they control the engine? I dont see any wiring running from the tender to the engine. Does it operate the engine through the power in the rails? I assume the tender is a pullalong unit Also is it possible to connect a Railsounds unit to the board plugged in like the Williams unit is without burning up the board or the railsounds unit?
The electronic board connected to the loudspeaker inside the tender is the Tru-Blast whistle sound board controller. The reversing board is inside the boiler of the steam locomotive wired to the motor.
