Thanks to our flooding last summer, we are doing some landscaping to divert future floods. As a result, along the back and one end of the house will be a terrace, faced with pavestone blocks. The capstones are 12 inches wide. What I want to do is run a double track down the top of the retaining wall, with a large loop at each end to send the train back on the other track. The loops will not be on the wall. Instead we'll have posts/roadbed supporting the loops. That will be the main line for the railroad. I can then have spurs and additional tracks running on the terrace itself. I've been researching, and think the 12 inch wide cap stones will be wide enough. Am I correct? Figure 3.5 inch wide track, along the edge of the cap stones gives me 8.5 inches center to center between the tracks. I could move the track .25 inches in on each side and still have 8 inches center to center. Is that enough?
I'm also seriously considering going radio control for it.
