I bought 2 of the Kalmbach books on DCC, then once I bought my Digitrax system, the manuals with it and the books gave me all I needed to know to get started, plus way more then I will most likely ever use.

Sound adds a very nice dimension to modeling.
But on the club layout, the sound level on some engines is too much, and I think become annoying. At home, running trains could be done at any time of day or night without worries, but could become a problem with sound. Fortunately, I believe most have a mute button to shut it off.

BigDaddyAs I stick around longer, I realize sound is controversial.
It depends - certainly online this appears to be true.
On the other hand, where I live almost every layout that I have visited has sound and DCC. Sound is not that controversial in my area. It has taken awhile, but just about every modeler I know has sound locomotives.

OliverHevvy But it sounds like today's DCC is well past that.
Yep!! Without a doubt the single greatest thing to happen in the hobby in the recent past. (Just an opinion - not a fact) After using analog blocks for many years DCC was a breath of fresh air. I think you will like it.
Hey Oliver!
Welcome to the forums and back to the hobby!!!
You definitely need to do some reading, and great suggestions on where to find information have been offered so I won't repeat them.
What I want to tell you is that DCC is easy to set up and get running. Certainly it can become very complex as you get into the details and learn to use more of its features, but for initial start up you can have a locomotive running in a few minutes. Therefore, I suggest spending your initial time choosing a system, then get a small piece of track set up, and then run a locomotive. After you have done that, then you can start to delve into the details.
As far as choosing a system, there have been lots of threads on the forums about which system is best. Basically, if I can boil all of the thoughts and comments down, the general opinion is that there are two main contenders - Digitrax and NCE. If you were to start a thread telling us what size layout you envisage and how many locomotives you would like to run (including other operaters on the layout if any), then we could help you fine tune your choices.
Personally, I am an NCE Power Cab user and I am very satisfied with the system. It meets all my current needs and it is expandable if needs be. Digitrax offers a few options that NCE does not, mostly in terms of communication and signals control, which you owe it to yourself to explore because they may appeal to you a lot, or not.
One additional suggestion. When you get your first sound equipped locomotive turn the volume way down. Otherwise it will drive you nuts!
Regards,
Dave
I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Greg,Nice,tidy and easy to wire DCC...
What's there not to like about DCC?
At one time I said a small one horse switching layout didn't need DCC and that still rings true but,IMHO Sound is far better with DCC then straight DC and that's when a small one horse switching layout needs DCC the most.

Hello all,
Welcome to the forums!
Volumes have been written regarding your seemingly simplistic question.
As Albert Einstein said, "When you 'open a can of worms' the only way to get all the worms back in the can is to use a bigger can."
There are many great websites that deal with DCC primer.
I suggest going to the NMRA website. Another source I've found is The DCC Guy.
Manufacturer's websites also can be helpful or confusing: TCS, Digitrax, NCE, and others are worth looking at.
As an electrician that lived through the evolution of dimmer control from analog to digital the difference between the two is that analog (DC) requires a separate control wire for each circuit and a return or negative, while a digital (DCC) only requires a single control and return wire for everything. (An extremely simplified explanation.)
DC control varies the voltage through a rheostat that excites the track. This variable voltage in turn excites the DC motor, turns gears and moves the locomotive.
DCC control is a constant voltage that sends "packets" of information; think of the way e-mail works.
Each information packet has an address code; similar to an e-mail address. Only the addressee "listens" to the commands coded in the packet. Just like the addressee of an e-mail opens and reads the "sent" message.
This communication is sent from the DCC controller to the onboard DCC mobile decoder on the locomotive or other such equipped rolling stock.
This is why each decoder has a specific address.
If two decoders (or more) share the same address then all will respond to the same command packets and all will perform the same specified movements.
The packets are "last command sent" priority. This means that you can send a packet information and the corresponding decoder will read that packet and execute that series of movements until the next packet overwrites the last command.
One decoder will hold the last command sent and then you can send another packet to a different decoder, specifying a different series of movements.
A mainline locomotive will run on the mainline track AND you can simultaneously run a switcher in the yard without having to power and unpower DC blocks.
Again, this is an extremely simplified explanation of what the potential DCC offers.
In my personal experience I should have adopted DCC initially rather than going though the dead-end expense of DC.
Hope this helps.
"Uhh...I didn’t know it was 'impossible' I just made it work...sorry"
no blocks, no panel switches, no cab control, control multiple locos on same track
Having not done my first DCC conversion, I don't have sound. My initial reading of sound was it was a must have, people seemed not to run their non sound engines once they converted to DCC
As I stick around longer, I realize sound is controversial. The people (50% statistically) who stick to DC are not unhappy. Others find sound a distraction. It doesn't "scale" well over HO distances. I cannot imagine liking "crew chatter"
I have only had 2 layouts, not counting the present one under construction. Neither had dual cab control. I am just 6 months ahead of you in getting back into MR and I am building a DCC small layout. Just testing tracks with my 2 DCC locos, I get a kick out of independendant control.
I'll get back to you on sound

After I put away my American Flyer trains back in 1961, I was out of the hobby until 2004 when I set up a small DC layout. The guys at my LHS persuaded me to convert to DCC so I could run multiple trains without block wiring. I bought an NCE PH-Pro 5 amp system, and the Owner's Manual told me everything that I needed to know, no books required. You should do the same.

Sir MadogSimply stated, with DC you control your trains by routing the power to those sections of track you want your train to run.
The flip side.. One usually set the blocks ahead and just let 'em run or used a power pack on simple layouts. On operation type layout a dispatcher was used in most cases.
In DCC its wise to have "power" blocks on large layouts in case there is a short.
My last ISL didn't have blocks just two wires from the Tech 6 to the track and by a simple push of a button I went to DCC mode. Push the botton again and its DC.
Simply stated, with DC you control your trains by routing the power to those sections of track you want your train to run. With DCC, however, you control the loco. This allows you to control more than one loco on the same stretch of track while at the same time reducing the amount of wiring on your layout.
DCC also has some value added features, like selecting performance characteristics of your loco, slow speed performance, momentum, acceleration and deceleration etc.
You don´t need to be an electronics expert to get DCC up and running, just two wires to your command station is all you need.
This may help as well. Part 1 and 2. You tube has lots of DCC tutorials.

There are hundreds of DCC links on the Internet. Here is one. Do a lot of research.
There are digital control systems that are wireless battery operated for HO scale also. Not DCC. DCC is the NMRA design. DCS is similar.
Some use smartphones and iPads.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I have DCC Guide by Dan Fiehmann and DCC Vol 2 Projects and Applications by Polsgrove and Popp.
It's a steep learning curve, but it's not brain surgery either. I think it's a bit like genetics. There isn't one gene for ugly and there may be more than one CV for the parameter you want to program.
Welcome back to the fun. Some folks aren't keen on books but I like to start there and have several Kalmbach books on track, etc. I came back from earlier MR stints just in 2011 or so and I acquired the DCC Guide booklet you will see shown at the bottom of the page listed above. It's DCC focused and I thought it was quite good. I'm pretty sure I have the 1st edition and it was fine to cover all the basics. You might find it in a hobby shop if you have one nearby and avoid the shipping.
When you want to get deeper, of course you can peruse old threads here. The Search the Community box on the right doesn't work so great. Usually better to search with Google (not Edge) as in: "site: cs.trains (your topic). Here's a search example on "DCC turnout wiring".

For more depth, there are great websites, including Allen Gartner's. Look under DCC Topics and there's a wealth of info.

Modeling HO with a transition era UP bent
Hi Oliver!
Welcome to the forums, and welcome back to model railroading.
Our DCC columnist, Larry Puckett, recently published a book on model railroad wiring. In it, he also explains Digital Command Control (DCC).
Here's a link to the page where you can buy the book:
https://kalmbachhobbystore.com/product/book/12491
At the bottom of the page, you should also see some DCC-specific books.
Happy modeling!

I was an active HO modeler up until the early 1980s, then life happened. ;-) I'm semi-retired now, and getting back into it. Can you recommend an article or book that is a good introduction to DCC? There's lots of how-to articles about adapting, programming, tuning, etc. but I have not much on the basics.
I do recall in the early 80s there was a sort of pulse-width control system, 16 channels if I remember right, that was starting to take off. But it sounds like today's DCC is well past that.
