MTH TIU and Lionchief Power

Actual model numbers are useful when you ask questions like this.

It could be that you have the polarity reversed as PS/2 likes the polarity to the board to be correct.  Since the LC power brick puts out DC, the positive side should go to the red terminal, and the negative side should go to the black terminal.  When connecting the TIU to the track, red terminal to middle rail, black terminal to outside rails.

That should work fine.

FWIW, I use a DC bench power supply connected to Fixed #1 to load sound files on my bench, so I can verify 100% that arrangement will work.

I must be missing something.  Given the picture posted above, how would the DCS signal get to the track when wires are only connected to the input on IN1, and nothing connected from the output to the track?

Should the LC power brick be connected to the IN1 input and the output be connected to the fastrack terminal track?

Thanks, Gunrunnerjohn.  The TIU is MTH 50-1001, the Lionchief power brick is Lionel 6-81603.  My purpose was to make a single stretch of track to run a Lo-V subway on an out-and-back programmed route.

I got it to work in the end but not the way I expected.  I used the Lionchief power brick (6-81603) to supply power to the track.  I used a Lionel Fastrack terminal track (6-12016) to get a pair of wires out to the TIU (MTH 50-1001).  What I tried at first - and what didn't work - was wiring the track into the TIU inputs (specifically Fixed Voltage In1).   When I tried that, there was power in the track (and in the engine), but the Lo-V wouldn't respond to the DCS remote control.  Instead, I wired the Fastrack into the TIU outputs (Fixed (DCS) Out1).  That worked.

So what was successful in the end was: power from the wall to the track by way of the Lionchief power brick (6-81603).  Wire the tracks into the TIU output terminal (Fixed (DCS) Out1).  Then I can control the PS3 engine (a Lo-V subway car) from the MTH DCS remote.

Now if only I could make the out-and-back programming work...
