O Scale - Standards

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:

    With his brows knit, his mind made up, his will resolved and resistless, he advances, crashing his way through the host of weak, half-formed, dilettante opinions, honest and dishonest ways of thinking, with their standards raised, sentimentalities and conjectures, and tramples them all into dust. See how he prevails; you don’t even hear the groans of the wounded and dying.
    Henry David Thoreau (1817–1862)

    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)

    In this nation I see tens of millions of its citizens, a substantial part of its whole population, who at this very moment are denied the greater part of what the very lowest standards of today call the necessities of life. I see one third of a nation ill-housed, ill-clad, ill-nourished. The test of our progress is not whether we add more to the abundance of those who have much, it is whether we provide enough for those who have too little.
    Franklin D. Roosevelt (1882–1945)
