GUNRUNNERJOHN - i get you product numbers when i get home
Why would you use the ZW if each train has its own power supply? The ZW is its own power supply. Is this a modern ZW or a pre-1967 ZW? I'm confused.

For one thing;more available amps are in a Z(Or ZW or ZW-C or ZW-L or etc) than a wall wart.
...maybe the freight set engine now pulls incandescently lit passenger cars and needs more amps?
Maybe there is only one wall outlet? No room for multiple warts.
Runs conventional trains on the same tracks; i.e., simply convenient.
Nostalgic ZW throttles are reason enough imo😁
Loops connected by a "mainline"? There is a lot you can do with that, including double duty on some loops as reverse loops.
Gramps had small loops 0-31/36/42-ish connected by big main loops (18x30'ish). It allowed the younger kids to run the small loops "unattended" while the elders controlled the turnouts/throttles that interconnected them.
You know making blocks are as simple as plastic track pins for isolating the center rail, and new power wire(s) for each block. Maybe add a switch to kill/enable power to that block.... or one to select which power supply feeds that block...or both.. etc. (All will likely share the common/outside rails, you just need to route the "hots" to where you want it, when you want it (a switch), and from where you choose (a switch)
A track plan makes it easier to elaborate on "best" wiring 
There are simply tons of possible combos for laying track and wires both.
If you run Windows try playing with some software. SCARM or Anyrail; both offered (limited track) free versions last I looked. Scarm can do more but has a learning curve; Anyrail is very easy to use.
