If I am using a 1033 transformer, and I want my O22 switch tracks to be powered via the fixed voyage plug, what terminal on the 1033 do I use /

U to center rail

C to switch plug
On a 1033 the only post that is common to a both a variable output and a fixed output is the B post. It must be connected to the outside rails. The U post becomes the "hot" post. The C post supplies fixed 14 volts (from memory...might be 16) also referenced to the B post.
This information is printed right on the label of the transformer.
Using B to the outside rail will only give me 0-11 volts for track power, correct ?
If that's what it says on the label...I guess so.
The 1033 was one of the more simple transformers for the beginners' sets. They did not assume fixed voltage for switches and other complicated (to a beginner) wiring schemes. Sounds like you need to upgrade to a larger transformer, or if you like them, get a second 1033 and put them in phase.
I would use
U to center rail
A to outside rails
C to switches
For 5-16 volts for the train & 16 volts to the switches for a good snap.
I was going to use the 1033 for a small, 3 x 6 foot Christmas layout with four O22s. I may have to use the KW I have but it's a bit large for where I want to place it.

That's what I figured after reading Arthur's response. I wasn't thinking outside the box. Never thought to connect the U post to the center rail.
Dan, just be aware that the KW only gives you the choice of 6 volts(too low) or 20 volts(too high) for fixed voltage settings. If you use the KW, use the A-U for the train and the B-U for the switches so you can fine tune them for good action in the 14-16 volt range.
Mea culpa. From memory, or lack thereof, I should have suggested A for the outside rails. I had forgotten that C was also referenced to A.
U to center rails
A to middle rail (variable to 16 Volts)
C to switches (fixed 16 Volts)
U to center rail (variable to 16 Volts)
A to outside running rails (Common)
C to switches (fixed 16 Volts)
On the 1033/1044, the "U" is connected to the transformer tap/wiper and the whistle circuitry, "A" is common(as per convention with Lionel single train transformers).
So I have completed my Christmas layout using the fixed voltage plugs wired to terminal "C" on my 1033 transformer. Everything works well. However, before I wired the controllers to the switches, but with the fixed voltage plugs already hooked up to the transformer, when I turn the track power on the switch track lanterns light up. It's been many years since I had a Lionel layout, but I don't recall the lanterns lighting when I used the fixed voltage plugs back then.
Gentlemen,
Rob is also right about the KW, I never used it for my 022, 711 or 072 switches, the voltage delivery was either too high or to low. I ran all my switches from an old ZW, setting the exact voltage with the arm as to the number of old 711/072's or 022's that were drawing power. Also remember to put LED's in the switch and in the controllers. However if Dan has no room for a KW, he will definitely not have room for the ZW either.

Unless someone has rewired the 022 internally, or there is an internal contact failure, inserting the plug should disconnect the switch from track power. You may have an external wiring error. If you power up the switch feed, do tracks get powered?
No, there is no power to the tracks. The lanterns are lit, the fixed voltage plugs are inserted and the throttle is off, yet the lanterns are lit.
I should add that when all of the controllers are hooked up, the switch tracks work properly. It's when the controllers are not wired to the switch tracks, but the fixed voltage plugs are, that the lanterns light even without track power on.
Lanterns in the switch motors should be lit whenever power is applied to the fixed voltage plug, regardless of whether or not controllers are connected or track power is applied.
I stand corrected. You are correct, RJR.

Completely normal. The lanterns will light with whichever power source is being used for the switch. Since 1938.
Thanks Rob. I must have been having a brain freeze. Wait, doesn't one need a brain for it to freeze.....LOL
