I get a lot of questions about wiring
for Digital Command Control.
This web page is my way of giving something back to the
hobby. I intend this web page for all systems. I hope you enjoy
I am an electrical and computer
engineer with experience in computers, radio (which has more to
do with DCC than you realize!), industrial wiring, troubleshooting,
and the electrical knowledge and wiring problems of model railroaders.
You will find this website is large
and comprehensive. As large as it is, I could probably double
its size if I had the time. If you don't find the information
you need, I have links to others who have
written about DCC. Contrary to what some may think, I really
do try to help the beginning DCC model railroader. For advanced
topics in DCC, visit Mark Gurries' website at: https://sites.google.com/site/markgurries/home

The popularity of this page has
amazed me. I regret I can only answer some questions through
Forum. Many thanks to all who help answer questions on the
Q&A Forum. I want to acknowledge that this website is the
cumulative knowledge of many people. If you have a tip I
can pass along, please send it to me.
Thank you in advance! Together we can make this the definitive
website on wiring for DCC. You may want to check the "What's
New" section below about once a month or join the Q&A
Forum to receive update announcements.
This page will not draw on non-periodical
published material. The intent of this page is to foster
growth of the DCC industry so that we as the end user ultimately
get even better DCC equipment. This page is not intended
to steal the thunder of those trying to sell printed material
to benefit the DCC industry. This page will simply refer
you to these fine documents.

If you are not capable and willing to assume responsibility for
your own actions, do you really think I would be foolish enough
to do so for you?
Thank you for the encouraging e-mail. It helps justify to
my wife the amount of time I spend on this page!
DCC: A Totally New Way to Operate Trains -
A Totally New Way to Wire!
Some modelers have a desire to wire
DCC like they did for DC throttles. After all, it worked fine
DCC is gives you the ability to
make your wiring more consistent - that is, fewer special wiring
situations - which translate to easier troubleshooting. Why not
take advantage of every opportunity to make troubleshooting easier?
For me, the more consistent things are at work, the less likely
I am to get woken up in the middle of the night!
DCC boosters also put out 3 - 10
times more power than a conventional power pack. While any given
locomotive doesn't normally draw 5 amps of power, your wiring,
switch machines, etc. will be carrying 5 amps during a short.
So seriously consider wiring in
a way that is right for DCC.
