The Z 4000 runs the track & switches and Z1000 is connected to a Ross Custom Switches Turntable. When the engine comes on the Turntable all kinds of sparks from the wheels and the Remote doesn't stop the engine on the Turntable or the whisker tracks into the Roundhouse. The back wall of the RH does. The Z4000 operate the Whiskers & RH tracks. Barry's book suggested a separate Power source. Z1000 is the Power source. Is another TIU needed?
