As an electrical contractor I came across a large O gauge layout in a house I was renovating many years ago. I probably spent more time in the train room than I did working on the house. 😂
The new owner was a newbie so I offered to "help" get the layout back in running condition. It was very well built all conventional with block controls to manage the trains. We were able to get 4 trains running on three mains with the blocks controlling two on the largest main line.
Thanks for sharing the article.
