The differences in the various O gauge and O scale standards can be confusing. O gauge model railroad tracks typically have their rails spaced 1 1⁄4" or 32mm apart with the National Model Railroad Association (NMRA) standard allowing spacings between 31.75mm and 32.64mm.

Famous quotes containing the word standards:
“As long as our people quote English standards they dwarf their own proportions.”
—Ralph Waldo Emerson (1803–1882)
“The technologist was the final guise of the white missionary, industrialization the last gospel of a dying race and living standards a substitute for a purpose in living.”
—Max Frisch (1911–1991)
“Our ego ideal is precious to us because it repairs a loss of our earlier childhood, the loss of our image of self as perfect and whole, the loss of a major portion of our infantile, limitless, ain’t-I-wonderful narcissism which we had to give up in the face of compelling reality. Modified and reshaped into ethical goals and moral standards and a vision of what at our finest we might be, our dream of perfection lives on—our lost narcissism lives on—in our ego ideal.”
—Judith Viorst (20th century)
