You're both worrying me, I didn't think there were many options! Are the wheels in the 4-axle 3-2 sets oversize too? Haven't they done anything with 2-rail wheels offered in the 90s? I'm not being picky, the oversize wheels may not fit without jamming up with brake shoes - like the 33" wheels in the 6-wheel passenger car trucks. Yeh OK they're probably off the wooden passenger cars from the 1890s, but.... OK dogs, time for a walk.
