MTH Z1000 Brick; Can it power multiple IR Receiver units?

The DCS Remote Commander uses a "negligible" amount of power relative to the 100 Watts that a Z-1000 brick can provide... maybe 1 Watt.

But I'm a bit confused as to how you would be using 2 Remote Commanders.  Do you have 2 physically separate loops of track or 2 electrically isolated sections of track each controlled by its own Remote Commander?  How do you insure that pressing a button on the handheld remote controls only one of the base units (unless you can physically isolate the receivers and skillfully "aim" the remote at only one of the two base units.

Thanks Stan.  Just so you know, my question wasn't so much regarding how much power the brick would be putting out, it was whether or not the power feed in the cord from the brick to the IR Receiver could be run through a splitter of some sort in order to provide power to multiple IR Receivers.  My plan is to have 2 separate physically separate loops of track on my ceiling layout, each with its own Brick/IR set up on either side of the room so IR signals are isolated.

However, after my test run this evening, it looks like that may not be possible and that I'll have to use the MTH power set up on only one of the loops (Track #1).  With the well known limitations of the IR receivers, the "skillful" aiming is put to a challenge when one is looking up at the ceiling as compared to down on a table.  The operation of a ceiling train basically locks your eyes and brain on the train more so than on a table layout and there are some blind spots when one is looking up.  So instead of having the IR receiver on the opposite corner controlling Track #2, I'm going to have to have both IR receivers control the same track from different vantage points.  For extra peace of mind I was thinking of placing IR receivers in all 4 corners of the room and having the two receivers on each side controlled by the same brick if possible.  If that is not the case, and it is looking that way, then I'll just buy two extra bricks and power each IR Receiver the standard way.   

If still brain-storming, one of the cleverest ideas I've ever seen on OGR was a so-called "RF Battery."  In this OGR thread such a gadget was used in a DCS Remote Commander to convert the IR remote to an RF remote...so skillful aiming is not required!  You kind of have to read how it works twice to "get it" but it truly is a clever idea for which the company received a well-deserved patent. I don't have one myself so can't answer any questions but it may have some application in your situation ... or if nothing else may trigger additional outside-the-box thinking.  In round numbers it costs the same as having to buy an additional DCS Remote Commander system!
