I did a lot of research before I built my N gauge layout. If you can afford it, go with Kato track & switches. There is nothing better. Just my opinion.

The members have done a good job of answering your questions,
however, it seems that you need a bit of explanation of the DCC system.

The DCC controller puts a continuous approximately 14 volts modified AC on the
track at all times. This powers the locomotive decoders and at the same
time transmits digital control information from the controller to the loco decoder.
As, our guys have stressed, a bus with track drops every 6 feet or
so is necessary to provide continuous even power. It is also important
to have clean rails and loco wheels for good power pickup.

Each loco decoder has a specific 2 or 4 digit 'address' When this 'address'
is selected on the controller, you can 'tell' the loco to go forward or backward,
and also control the speed. Further, when you get loco A running, it will
continue at your set speed while you punch in for loco B. You can then get
it running, and go on to loco C (and so on). By punching on the
'throttle' (which is much like a TV remote, usually with a small digital screen)
you can go back and forth from loco to loco actually operating each
loco on the system.

Because of mechanical friction the speed of locos can vary, so attention
to train operations is important, else even tho you have carefully adjusted
each locos speed, there remains the probability of a collision, which on
an elevated layout could be fatal to the locos. The decoders will not
automatically adjust the speed beyond what you
have set using your DCC controller.
