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 this website.
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:

a tip I can pass along, please send it

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.

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
A Totally New Way
Some modelers have a desire to wire DCC like they
did for DC throttles. After all, it worked fine for DC.
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. Not good!
So seriously consider wiring in a way that is right
