All kidding aside, I have notice that I can draw a continuous 8 amps and not over heat my transformers, the ZW's would get very hot. So warm that the room started to become uncomfortable (when you have four going at once).
The integrated Legacy control is fantastic, and I cannot wait run/experiment with conventional engines that I could not run before. No more TPC 300/400.
Circuit breaker protection is above the ZW and you no longer need the battery houses
Its nice to know if you are loosing the Legacy/TMCC signal - the transformer 'Lionel' light will flash.
So Bigger is not only better, but with many improved features for operators like us... this one gets my two thumbs up!
