Kelly,

I'm not sure exactly what you mean by "in phase" but I think I might help.

When wiring multiple tracks as in your situation, you do want to be
sure they are all wired with the correct "polarity."  A simple way to
check this is to use an automotive tester.  This is a tool that looks
a little like a screwdriver with a wire coming out the handle end. 
The tip is a point instead of a screwdriver blade, the wire usually
has an alligator clip on the back end, and there is a bulb in the
handle.  You want the kind without a battery.  That kind is a
"continuity tester" and doesn't work for this application.  You can
find this tool at any automotive parts store, as well as the
department stores having an automotive section.

The above tester uses a 12 vold automotive bulb for testing 12v
automotive circuits.  As long as your power supply delivers less than
15v it should work fine.  If you are using a DCC system, which is
usually 18v, you may need to change the bulb to a higher voltage.

To use the tester, apply power to the track(s) you want to test.  Clip
the alligator clip to one rail (for example the turntable lead track)
and use the probe on other rails to test correctness.

1. Test the opposite rail of the same track.  The bulb should light
up.  If it doesn't, either there is no power to the track, or the bulb
is bad.

2. Test the SAME rail on the track section you want to check (for
example on the turntable).  The bulb should NOT light up if the track
is wired correctly.

3. Test the opposite rail on that same section of track.  This time
the bulb should light up.

4. If you are testing multiple track sections (for example your
roundhouse tracks) go through the same test when each section of track
is powered.

5. When you have completed the above, attach the alligator clip to the
OPPOSITE rail and repeat the tests.  This will assure that the other
side of the track is wired correctly.

NOTE:
It should not be difficult to obtain correct wiring without resorting
to the above methodology.  Simply make sure all the "North" rails are
wired to the same power feed, and make sure all the "South" rails are
wired to the other power feed.

By "power feed" I do not mean directly to the throttle.  The power
feed I am referring to is the power to the tracks after your block
control switches (if you are not using DCC), or your isolation
switches (if you ARE using DCC).  This of course assumes that you have
been able to wire up to that point by correctly isolating "North" and
"South" polarities....

Ask more questions if you don't understand this, or need further
explanation.
