Building the roundhouse at Mount Forest...

David, the HH2 powers only the turntable motor, while the track on the turntable is track-powered, and can be turned on or off, and controlled directionally by  switches on the layout facia.  The roundhouse tracks are powered through a rotary switch, which is also controlled by a separate switch which supplies the power.  With the exception of the turntable motor, it's pretty-well the same set-up as at the Lowbanks engine shop...
