Happy New Year!
This is the first use of the modern ZW. After a few hours (over several days) of running both A & D had lost all power. The bricks were not tripped. The B & C rings had full power. The club house layout has two simple independent loops and a reversing trolley. Due to the press of the Christmas season and the need to keep our clubhouse display running, I disconnected the trolley and moved the train controls to B & C. The B & C worked OK with the TMCC. Now that things have calmed down, I'd like to resolve this.
