Would Like to Add DCS But......

One TIU will control 4 "power districts".  You can probably do fine starting with 2 TIUs.

One MTHDCS Remote will control all TIUs.

For Wifi you need one WIU for each TIU and one smart phone or tablet.

don't do it!

Heck yea - Do it.  If I didn't have DCS I'd do it just so I could have some of the MTH A.T.&S.F. plated E8s!  Man, are they pretty...

Do it, you’ll love it

Do i have to alter existing wiring?

Your asking for double the problems= frustration. Have fun instead!

Probably not. Just this week I brought my DCS system to our new large club layout to try it out. It is 25' x 43' and has 4 or 5 loops of Gargraves track and was not wired with DCS in mind. Mostly a single buss for each loop I think. I added the TIU with small alligator clips to a siding on the outside loop and ran a Premiere diesel around the outer loop. It appeared to be a solid connection and all went well.

You can always tweek it if necessary if you encounter problems.

Go for it.  If you are using Gargraves or Atlas track, hit my email and I can pass on some good information to help you that will work great on an existing layout.

go for it!!!!     

I have always had DCS and love it.

There is plenty of expertise on this forum to see you through the process. Recommend you get Barry's e-book to get the train out of the shed.

It depends how you run your trains, but I believe you could start with one TIU.

Greatest part of d's, is you can run your legacy engines with mth. Honestly the dcs app on an iPad is the best way I've run trains. I think it controls legacy better than any remote. Try it with a phone then an iPad. It' great

I have both Legacy and DCS and have no problems.  I also have Wi-Fi, but you don’t need that immediately.

Each TIU can support 4 of your power districts.  So, as Susan said, you will need 2 TIU’s to cover your 6 districts.  You only need a small change in your wiring to insert the TIU between your power source and the track.  Each pair of wires from the transformer for a district will go to one of the input pairs on the TIU.  The wires to the track connect to the output pair.  Connect the Legacy wire to any of the ground terminals on the output side of the TIU.  That’s it.

As Scott said, if you are going to use DCS, Barry’s book will answer your questions.

T4TT,

   I also run DCS & Legacy, I highly recommend running both.  If you are running FasTrack drop me some e-mail I will help you out.  Pine-Creek@live.com

Try adding DCS to your layout without rewiring completely and see what happens.  I ran DCS 1st then added Legacy, a lot easier most times.

I also recommend the OGR Video Guide to DCS, especially for those just adding DCS.  Rich Melvin does a great job explaining 90% of what you need to know about DCS and for a visual learner this Video is just fantastic.  It starts from the very basics and moves to the more complex,.

Barry's O Gauge Companion book is a must for DCS running, covers everything in depth and his technical direction rivals the NASA Engineering Technical Direction writing, we did while building the Space Shuttle.  Simply outstanding technical writing, well worth the money expended.

Hi T4TT

In this video we will use the MTH DCS Wi-Fi to operated a new RailKing Amtrak Genesis, Amtrak Salutes Our Veterans. I will show you how to program the Premium APP that operates this locomotive along with how to program this loco for MTH-DCS along with other model train operations.

I will also say: "Go for it"
