> Is there an online tutorial or summation of features of DCC?
> Roy Inman
Roy...I am not certain about the tutorial and have not heard of one. As far
as a summation of features, I would suggest asking that question on one of
the DCC-oriented Yahoo Groups Lists. The NCE-DCC list is my personal
favorite and the folks there might have some good thoughts on the matter.
If you like, we here on the S-scale List can accumulate a features list for
you, but I suspect there is one somewhere else already prepared.
Basically stated, the main feature is the operation of many locomotives
WITHOUT the use of block power toggle switches. No more throwing a toggle
switch every minute (or less) like in the good old days. You can keep yer
eyes on the train instead of constantly looking at a control panel and
trying to figure out where your train is at. Each loco can be independently
controlled by the operator. Another basic benefit is that locos can be
speed matched so that double heading and/or pusher service becomes possible.
If desired, you could make a Shay and an Atlantic run at exactly the same
speed. Then, there are the functions. Each function can be thought of as a
switch that can be turned on/off for whatever reason you can imagine. For
example, headlight, smoke, whistle, uncoupling, etc., etc., etc. I believe
there are up to 25+ functions available per the NMRA specs. Some decoders
(installed in loco) have all 25+ functions while others have a lesser
number. DCC can also be used, if desired, to throw turnout motors, operate
accessories, run turntables, signal systems, etc. All of this can be done
from your cab/throttle if desired. Anything that operates from a voltage
can be operated from DCC. DCC also can be integrated into your computer so
that a Dispatcher can sit at a garden variety home computer and control the
layout just the way a real Dispatcher does it for the prototype. The track
diagram is on the monitor and the mouse can throw turnouts and control
signals if desired. If there is a computer whiz in your club, he can
totally automate your modular layout for display running at exhibitions to
include switching, passing track operation, yard operations, and so forth.
Be forewarned, computer automation is a very expensive and time consuming
thing to create, but it is quite possible. All of the above are very
difficult, if not impossible, to accomplish with conventional DC. DCC can
be very complex or rather simple. It all depends on what you want to do
with it. Much of the perceived complexity comes from folks playing
one-upmanship with each other.
I am sure other folks can add to this list of features and make it very long
indeed. But I will stop here because you now have the essence of DCC.
