Welcome to the forum. You'll be amazed at the wealth of modeling information this group offers. Although it was quite some time ago, I also converted from old school DC to the wonderful world of DCC.
Converting a DC layout to DCC is usually pretty simple. If the layout is powered by a single DC power pack, disconnect the two wires from between the track and the power pack, then connect those two wires to the "track" terminals of the new DCC Command Station/Booster. That's it! If your trains slow down on a particular section of track, you might want to run a few new feeder wires between such sections and the DCC unit. However, it really is just two wires.
If the layout is set up for cab control DC operation (multiple trains), flip all of the track block switches to one "cab", then connect the track wires for that power pack "cab" to the new DCC unit. Again, that's it. Yes, you will hear from all sorts of modelers that it's not that simple. Yet I am part of the crew that operates multiple trains on an 8 1/2' by 11' HO scale double decked layout that was converted from the old Atlas style cab control to a Digitrax DCC system in just this way with no upgrades to the wiring sizes. In fact, the old Atlas Selector switches are still in place but taped over. This layout was featured in Model Railroader a few years ago and it continues to run quite well.
As far as which system to use, OH BOY will that start an argument! Many forum members will swear by one brand of DCC system which could just become the system you only swear at! I have used Atlas, Bachmann EZ Command, CVP, Digitrax, MRC and NCE DCC systems and all have their own advantages and disadvantages as well as price points. The Atlas and Bachmann systems are very basic but do provide actual DCC operation. The Atlas (Lenz) system might be a little hard to find anymore but the Bachmann EZ Command system is available both new and used. A cheap used unit could be a good way to introduce yourself to DCC without spending a lot of money. It will also show you how far the basic DCC features will take your layout while also exposing it's lack of features you might truly desire in a future upgrade system. The only problem with these basic systems is the difficulty in setting up multiple throttles for multiple operators (both you and your kids). It may be better to spend a little more to purchase a more full-featured starter system and add a second throttle. However, this is where things get sticky. Whatever approach you choose, get some hands on experience with actual DCC systems of different brands. The systems all work similarly so it really comes down to which throttles you like. Some throttles make you wish you had three hands while others are so well designed that you never need more than one hand. Visit local hobby shops near you to see what they use on their display layout. Visit a local club or two for the same reason. If possible, visit a few private layouts to see what systems they use. Your kids will probably learn the systems faster than you will so get their opinions, too.
Finally, one of the most popular systems also seems to be the most glitchy. I have attended several operating sessions where this brand of DCC system glitched so badly that the session had to be cancelled because the trains would no longer function properly. Yes, I have experienced glitches with other brand systems but never so bad that the session had to be aborted. Ask lot of questions. The more you know the better choices you can make. Most importantly, ask the question, "If you could go back and start all over again, which DCC system would you buy?"
You will have to install decoders in your existing DC loco fleet but that's not difficult if you have a little basic electrical knowledge and decent soldering skills. I would start by converting one or two locos with non-sound decoders (you can always add sound later). There are plenty of "how-to" videos on-line. The decoder wires are all color coded which makes the task much easier. Keep in mind that DCC will not make a poor running loco run better so make sure your locos run as well as possible on DC before your convert them.
Good Luck!

Hi Eveyone,
My name is Jason and I'm new to this forum. I have a old 4'x8' HO "The Yardmaster" layout track that my dad built for me when I was a kid. He used Atlas track and equipment and this all DC with several DC loco's. Fast forward 25 years... The track and layout are still in pretty great shape with some things not working, like the bell on the tyco train crossing, two turnouts don't work (have to move manually). The trains do work around the outer loop and the figure eight but it's DC power, so it's not nearly as smooth as DCC and hard to run two trains at once. I would love to get this layout up to date. Sounds like DCC is the way to go? I know very little about DCC. I am looking for suggestions, ideas, how to's, don't do, equipment that I would need to convert, and any and help would be greatly appreciated. My kids (8 and 6) love driving the train as is, but I would love to make this better with a couple of new modern locos to have even more fun. Thanks to all for help. I attached a few pics for you to get an idea of what I have.
