DCS wiring, common bus

Lou,

In my opinion (and experience) you should be able to just hook up a TIU and operate DCS, TMCC and conventional engines with only minor, easily correctable issues, if any at all.

Just be sure to purchase your DCS from an authorized MTH dealer and get the latest TIU, Rev. L.

If the DCS doesn't come with the latest software, DCS 6.1, it's easy to update the TIU and the remote. 

Everything that you need to know about DCS is all in MTH’s “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!

Absolutely no problem.  That's the way mine is set up.  Unless you have an ancient Rev G TIU, connect all of the TIU black output terminals together.  (Rev G had them connected internally,)

Thanks for the responses. I'm glad the DCS system will will work with my current layout wiring. I plan on picking up a brand new DCS system from my local hobby shop after the holidays, some time in mid January. Plan is to hook up the DCS system and get my two PS2 locomotives running well with it, then add a TMCC Command base for the TMCC locomotives.
