With no lights, now I call it a sleeping car!

Were the two PWZW's in phase and was the common, U, on the two of them connected?

I’ve been operating this layout with 3 post-war ZW’s for about 15 years and I made sure a long time ago that they were in phase. I keep them plugged into a terminal strip and each plug is marked with tape on end so that I will plug it in correctly when I do unplug any of them for maintenance, etc.
The U terminals of one are not directly wired to another but one U terminal from each transformer is wired to my common ground buss.
