Hello JJ.....
You bet'cha you can do that. Yes! If everything works well with DC, it will
also work well with DCC -- with one possible exception. Sometimes wheels
passive over turnouts graze the open point and create a momentary short
circuit. With DC, the momentum of the train carries it along a bit and the
short circuit goes away quickly. In many cases, all you see is a short
hesitation and most folks do not pay much attention to it. With DCC, the same
momentary short circuit can sometimes cause a circuit breaker to trip and shut
off the track power. The only way to know if this will be a problem is to test
it with DCC.
One way to prevent this problem is to use short-resistant turnouts which,
simply put, always have their point polarity the same as the adjacent stock
rail. Another way to prevent the problem is to make sure both the track and
the wheels are gauged properly.
Good luck...Ed L.
