Mark, looks like it will be fun operating the line. I cannot quite see the elevation marks at each track section. I assume the tunnel track has your lowest elevation and the bridge over section has the highest - everything flows up or down from there? I am surprised some of the grades are pushing 4% - I figure you have about 17 feet on the inner loop - with a 6 inch rise is just shy of a 3% grade; with a 4 inch rise is under 2% ; the outer loop would be even more gradual.

BTW we young guys have to stick together - we are probably a couple of months apart ; )
