Lionel ZW & 1044 used on the same common???

The A terminal is the "common" terminal, the U terminal goes to the center rail.  The B and C terminals are fixed voltage taps in reference to the A terminal.  Check the legends on the top, it shows you all of that info.

Got a question, If I want to use a Lionel 1044 transformer using / sharing  the same common as a ZW what is the common on the 1044?
 Is it the B post with the circuit breaker??  And what post would you connect to the outside rails? The B post also.

Kind of confusing.

 

 

See the diagram at the top of page 6 in the attached pdf file (it’s actually the page numbered “Page 2”  in the operating manual).

HTH,

Bill

The above answers may be incomplete, in that the transformers have to be phased, which may require altering the 120-volt line plug

So why is the U post common in the KW and ZW,  and the others are U to the center rail?

Thanks guys, I got it now but reading the Lionel manual it sure is nutty the way they had so many different ways to hook up their transformers. I will give it a try today.

Up-date:

After hooking it up,,,,,It don't matter anyhow. I found out the 1044 is not big enough to run all of my accessories and the 8 car postwar set behind the Lionel 2065 Hudson on the new elevated level. Too many lights and other stuff pulling on it. Think I will just run that train off a LW.

John, on the 1044 if I want to use the B and C posts to get the constant 11v which one is common. Or am I completely missing something here. Thank you 

Here are all the combinations of common grounds you can use. The 1044 shares the 1033 settings.

Actually, if you are only using 2 posts on a transformer to provide a fixed voltage,* it doesn't matter.  When properly phased with your other transformers, common on the transformer is whatever is connected to the common circuit.

It's a little more complicated if you want to use 3 posts to provide two different fixed voltages, but it can be done.

*If you plan on using a handle to vary voltage, there are other considerations.
