Thank you for taking the time to respond to my question. I have the book and after some time I figured out how to zone my layout.
Hi There
With the two loops of track you could run 2 trains . Are you using DC or DCC ?
Mr Shelby , I believe used a Electrical Block system using DC .
You could easy run two trains using DCC with no block system .

I'm looking at a book by him right, on Google. The book is "HO Railroad from Set to Scenery", and on page s 43 and 44, there is detailed track and wiring plan.

I'm not sure if the link will work, but you can give it try. If the link is not "hot", you can still copy and paste.

I have the book by Rick Selby, but the details for building a layout running 2 trains is a little vague. Does anyone have detailed track for this?
