QUOTE (Doug @ 6 Nov 2006, 14:28) <{POST_SNAPBACK}>Turntable implementation. This also need a reversing module as the loco is swinging around and you want to drive on and off without switching direction on the controller:

That depends on the design of the turntable and how the turntable tracks get their power. Some have a built in commutator arrangement that reverses the power for you and a reversing module is not required. If building a turntable from scratch it's easy to arrange this.

Or, if the loops are at the end of a dog-bone style layout, make the central section the reversing one using a single reverse module. You still need to be careful you don't have two trains bridging the isolation gaps at the same time.

If you can arrange auxilliary switches on your point motors (if you use them) then there's no need for a reverse unit at all. Just feed the appropriate polarity to the loop depending upon which way the points are set.
