Reply to "Confused on what I need for running my trains"

To give you guys an idea. When I started this 20+ years ago; people actually came here. Dads used to lay on the floor under the table with their small children to listen to the rumble while playing with cars. Hence, changing horses midstream. I was going to run wiring through the table framing and dress with a skirt. Then I over thought it about the small room illusion thing. I did the most ignorant way of finishing and wiring the layout. I dug ditches to run the wires on top of table. I have pics if anyone is interested.  I’m well aware of using relays for blocks. With these pics maybe you can see how I painted myself into a corner. Let me know if I rattle on too much.
