Ton of lites!!!

Many have used the Malibu outdoor lighting transformers available at the big box stores. Try and do a search, ithas been discussed many times. 600 watts for less than 100 dollars.  Can't remember all the details. I'm not at that point where i'm ready to light stuff up. I'm sure others will chime in. Good luck,

Have you considered converting some or all of the lighting to LED lighting?  Much less power required all around.  The last set of passenger cars I converted went from almost three amps to about 150 milli-amps total power, and I get better lighting as well.

If you are paralleling the ZWs literally,be careful to set the voltages exactly the same,otherwise they can back feed into each other resulting in damage.

Converting to LED lighting is also a good idea. Great for building lighting,however I have a lot of PW lamp posts on my layout which would not look good with LEDs in them.

I use the outdoor lighting transformers. I have 3, 600 watt ones. I divide them into 6 circuits fused with 10 amp fuses. This makes it easier to trace a short somewhere. The ones I have,Hampton Bay have an excellent breaker which trips before a fuse blows.

The LED strips are designed for 12VDC in so all that would be needed to use them is a rectifier in each building or make a DC buss with a single rectifier for all LEDs. I also use individual LEDs mounted on fish paper. Irregular shaped lighting strips can be made this way. Shown here is a basic circuit

Dale, with the size of that layout you're building, I'm surprised that three 600W transformers is sufficient!
