My plans have had to change on my around the walls layout, now having to augment the ton of MTH Realtrax I already have, with a bit more, even though it is not considered the best. I have enough 54 inch curves, and room for 72 inch curves. The plan is simple, double track with two changeovers, one on each side of the room using 072 turnouts, one extra passing or siding on one side, and a few dead end spurs here and there. In the corners, I would like to maintain a look of realness, and not have a massive change in track separation. 54 inch and 72 inch are 18 inches different in diameter, does that work visually or should I go tighter with 042? Maybe start an outside curve with 72's and go to 54's, finishing with 72's? I will check clearances before securing the curvature with my longest cars/locos. Since this will not be coming apart for a long time, plan on adding jumpers underneath, soldered to the friction contacts between sections to eliminate the intermittents that will surely arrive at some point.
