@bmoran4 posted:AC power is what you need for the UCS and just about all 3 rail O Gauge items. Some of the LionChief family come with the less capable small cost reduced DC power supplies which go against the over century of tradition and compatibility. Fortunately all LionChief equipment can run on AC power so the question boils down to your transformer.
He has the typical Lionel 18V DC power pack to power the tracks, but what I wanted to know is if there is a way to run the UCS tracks with a fixed voltage AC power supply in conjunction with it. I was thinking of a doorbell transformer to be specific. He has a Fastrack uncoupling track for his outer loop, but his inside loops have three sidings and I wanted to add in a postwar UCS in two of them. The track power on both sidings can be switched on and off (Center rail switches).
Thanks,
John
