Well, I did it. Last night I pulled the 2 CWs off the layout and put up the ZW. Ran everything carefully to avoid a derail. Every loco I tested that did not run with the CWs runs with the ZW. I'm still waiting for the #91 circuit breakers to test the MTH. I have a Kline/RMT switcher conventional that would not run and it is fine now. A MPC 4-4-2 that would not run with the CWs is running now but that might be the E unit. After a few runs around the layout it started running in reverse only. The MPC 44 tonner was quieter. My conventional early 2000s RS-3 that was not particularly loud was even quieter. I can't wait to get the Christmas stuff out. I have a RMT Beep that completely spazzed out last Christmas. I suspect it will be fine now.
Had a rough day at work yesterday. Company wide outage of a critical system. I worked with a tech all day, then had to run my stuff manually. So a bit of bourbon and properly running trains was heaven.
Old school rules!
