I got my "scale" wheelsets from Lionel today. I checked one for gauge and it's slightly wide, easy to fix.
The wheels appear by dial caliper to be exactly 1/8 inch wide, which is 0.125 inch, for a "code" 125 or 8 scale inch width. A standard RR wheel has a width of 5½ - 5¾ inches, so Lionel is close enough for me. Tom Hawley -- Lansing Michigan
