What year and type are these transformers?

 

[T-Man]

They are prewar Type T from what I see. I will check the reference. I hope you are using something more modern.
The T was made throught 1925 to 1938 and rated at 100 watts. The 1925 version had a light socket adapter.The 1938 had a two prong plug. It is listed in both cats so I am guessing on production years . I can't tell you when it stopped. Unless the year is on the case.

Nice call, T-man!

Thanks for that great info.

I been working on my reference collection. My book had pictures from the actual cat so I can't give you a value.

On this T type there are a bunch of lettered posts, how were these used or connected?

Chart

I found this great chart but the guy locked it down and I cant print it out.

The service manuals have the charts. The blue hardcover runs about 50 now for postwar service. To anwer the question U is the common, A etc is normally the voltage across to u. Each transformer can be different. Some are variable to run the train the others are fixed for accessories like lights and switches and decouplers. Each transformer has it's own chart.

I looked around and I have only a Prewar N at 50 watts and this American Flyer.

I don't think that they have to much value.
Unless it's in brand new shape.
If you do use it make sure the power cord is in good shape.

The ZW's are a different story though.

The T transformers in my guide says it was made from 1919 through 1928
In 75,100 and 150 watts.

Price is put at in $10 bucks in good shape to $30 bucks in excellent shape.

(my guide book is from 2007 so it might have went up a little now)
