A DCS remote with the Z-4000 Remote Commander Receiver (40-4002) installed on your Z-4000 transformer will allow you to dial up the voltage remotely without touching the transformer using Z4K tracks. The handles stay in the off position.
You can also run conventional engines by varying the voltage with the remote.
I don’t supppse I can control it with a legacy remote if I add an MTH TIU can I?
No. What Joe is referring to is a remote control receiver module that can plug into the Z4000. It is controllable via a remote that was made for it (which allows control of the Z4000 voltage output), or the more versatile DCS remote, but that is a huge overkill for your needs since you have suggested using Legacy Trains, and not said anything about using trains with DCS>

Scratch that..... all of my track is atlas.
Z4K tracks is not actually a track type, it's a name for the control of the voltage using the remote. Any track system is compatible.
I agree with Rod. For what you have suggested(assuming you already have trains picked out that have directed your mention of using Legacy), you should get the 180 W brick(s), and possibly a Power Master to go with it (them). If you skip the Power Master you won't have remote control of the halt function, which I would think might be desirable for a ceiling mounted layout. (But may depend on how accessible your physical switch for the AC main outlet powering the bricks is - for a small bedroom, it may be just as easy to dash to a wall switch that will kill the Power Houses vs hitting the halt button)
