Howdy ya’ll ! Last night around 6:30pm the UPS man brought me a beutiful brand new Lionel ZW! Wow this thing is nice! it has the 2-180 bricks and man are they beefy. Until now I’ve just been using cw-80 and they are ok. But I needed power for expansion! And I read so many great things about them I finally had the extra cash for it. It is up and running 2 seperate loops of Thomas and friends already with 2 tmcc loops in the future. Thanks for all the advice you guys share on this web site.
