I need a little help in understanding exactly how the Wabbit works. I want to build a mountainous section of track on a peninsula of my layout. To get the maximum curves I want a reverse loop on both ends of a 30 foot rising track section (this will not tie into my main line) and I want continuous run. In reading about the Wabbit, it seems to do what I want, but I have a few questions. Do I still need an auto reverse unit or is it part of the Wabbit circuitry? Do I need a sensor to determine train location (the reverse loop will be much larger than any train I would run)? Will one Wabbit run both tortoises at each of the seperate loops? This seems too simple so I'm afraid I'm missing something.

Ron,
The Wabbit with 'Auto Throw' the turnout so that it is aligned correctly as a train approaches from the frog end of the turnout. It does not change the 'polarity'(either DC or DCC). The complete manual is available on-line:

A little more information. The 'sensor' is just a gap cut in the track - nothing special. And as I have mentioned, you will need to handle polarity changing with something else....
