2878 forum posts 248 photos	Wow, that is technical, and not sure I understand it. It states 5" as the minimum width between rails, and increasing on bends. I could not read into that what the maximum could be, for straight or curves.

34 forum posts 5 photos	I did not spot a max figure for gauge widening on their site. My interest is 7 1/4" and in the society standards they give a max widening of +1/8", so somewhere around + 1/16" should be OK for 5". CB

Source: Engineering in Miniature, Vol.15, number 8, January 1994, page 247; Locomotive Wheel Profiles, author Dr. Martin W Baker Doug Hewson gave similar limits (his max + 3/32 inch) in earlier articles, and gave the 5" gauge widening for multi-gauge trackwork as 5 1/16 inch through the pointwork.

2878 forum posts 248 photos	So in engineering terms 5 inch gauge is 5" +0.090, -0.000 for straight and bends, opening to the high limit on bend sections, however through points it should be 5" +0.063, -0.000. thanks Bob
