How many DCC trains can I run simultaneasly in one layout? Do I need any special connections to run more than 2 locomotives. I'm looking to run atleast 3 locomotive at 1 time on my layout.

Are the sound decoders add ons to the silent decoder? Or are they just 2 different boards based on your preference? I saw a picture online while researching about sound decoders and saw an install that had 2 digitrax boards hooked together and it was stated that one was the sound decoder. Was the other the dcc board?

Which dcc boards will work on my locomotives? I heard tsunami are better. If so, what board model should I get?

Yes, they were new in boxes. Purchased at a hobby shop. Some from Online stores. Thnx for the info.

The trains were new from a year ago. Ran them each about 10 - 15 minutes about once a every couple of weeks. They run great since last tested. My soldering skills are good to great. Modeling though I don't have the patient for gluing. Hopefully there is no gluing involve in converting the the boards.

Hi, I'm new to the this forum. I'm also new to HO trains. Doing it about a year now. My collections of HO trains are Bachmann's DC lines. I have a couple of GP30's, GP38-2's, SD40-2's, and a several F7's. Can I convert them to DCC? If yes, how do I go by doing that?
