I personally rather have the power sidings and use signals to control the
movement of the trains. Layouts shown in the 7777 train book are generally
impossible to recreate in a 9V layout because the sidings need power in
order to run more trains.

To use the 12V signal, take a look at:

Henry, other reasons to buy 12V stuff even if you're plan to operate a 9V
layout:
* 12V trains are very nice models and have good selection of parts.
* Cars can run on 9V also
* With the help of a 9V motor as power pickup, you can power the 12V motor
and have the cool moving rods on your steamlocomotive. (A great example of
this technique: http://www.royal-train.com/gallery_kathryn.jpg )
* In most trains the 12V motor can be easily replaced with a 9V one (7740,
7755, 7760) or the motorised tenders can be rebuild on top of a 9V motor.
