Design
The Superliners were the first Amtrak car type to be equipped with an onboard waste treatment and disposal system linked to all toilets. The initial design of this system retained toilet wastes until the train attained a preset speed (or a manually operated lever was moved) to dump the waste along the tracks beneath the moving train. Eventually a full-rentention system was installed that stopped this practice. Initially the cars could not be worked east of Chicago because of limited overhead clearances, but by the 1980s many eastern railroads had raised clearances on their tracks to permit tri-level auto-carriers and double stack container trains, which also permitted the operation of the Superliners.
The Superliner I and Superliner II differ somewhat in interior fittings, primarily in color - the newer cars tend toward gray, aquamarine, and salmon rather than the shades of brown and orange favored on earlier cars. Externally, the two classes differ in a number of subtle respects, but they are readily distinguished by the type of truck (bogie) the car uses: Superliner I cars use a German design originally fitted with an air bag suspension (replaced with springs), while the Superliner II cars use a General Steel Castings truck of the same type used on Horizon, Viewliner, and the original self-propelled 1969 Metroliner cars.

Famous quotes containing the word design:
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
