Good morning Joe,
Yes. I am home. My legs don't work so well these days.
We are planning on building a O Scale layout, we are still in the planning stage, how we want it to look and elevations etc. we found helpful material on this forum for that part. We are going to have three separate train track systems for the three eras that we want to model.
So yes we will be getting a transformer or transformers for the trains.
How do you tie the rails together?
