Standards
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 things a man has to have are hope and confidence in himself against odds, and sometimes he needs somebody, his pal or his mother or his wife or God, to give him that confidence. He’s got to have some inner standards worth fighting for or there won’t be any way to bring him into conflict. And he must be ready to choose death before dishonor without making too much song and dance about it. That’s all there is to it.”
—Clark Gable (1901–1960)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
