How to create or add bus wires to small layout?

Don, Wayne: Thanks for your feedback. I'm beginning to think you're right. I was asking about the bus wire thing b/c the layout will often work fine for days or weeks, and then trains will suddenly stall at certain locations and I have to get out my soldering iron again. So I have to experiment to find where the bad join is and then solder. And, yes, maybe I'll solder more wire joins to the problematic areas.
