How to set up TMCC

Roger, you do need a power supply to the track. but the most important thing (if Im reading your post right) do not hook up the signal wire from the command base to the middle rail!! that gets hooked up to the outside rail!....it goes like this....plug command base into wall outlet, run a single wire from command base to outside rail....then choose your transformer and hook it up to the track as you would for normal operation..ie; ZW, KW or similar then you can place command equipped locos on the track, power up the command base first, then raise your track voltage to 18V, and your command engines will instantly know they are on a command track.....hope that helps!...………...Pat

make sure you have a ground connected at the outlet!

Don't use a "cheater" 2 wire receptacle.

Thank you for the clarification!  So the outside rail I determine on our FastTrack power supply track piece?

yes, use the outside rail for the TMCC signal wire from the command base. does not matter which outside rail....the TMCC signal runs down the outside rail as a radio signal.

Here is a wiring diagram that I hope helps.  Depending on the transformer you are using, you may need the TVS and/or the fuse to help protect your command control engines.
