For those of you that are using the 5.5mm charging jack for your batteries, I assume that the center is + and the outer is -?
Bob,
i think that is what i use, but quite franly i have to check the wiring of one of my other locos every time i wire up a new one to be shure.

Bob,
I have converted most of my locomotives to battery and use that type power plug, and yes center is plus and outside is minus. I don’t think I have seen any commercial transformers that were different.
Great, thanks guys. Another ?, how do you wire the tangs on the plug? Do you have it cut out the electronics when its charging, or just plug right into the batteries?
Cut out the electronics when charging.
