The Quick Action Triple Valve
Although the plain automatic air brake was a great improvement over the straight air brake, in an emergency the system still applied the brakes to the last cars in a train later than to the first cars in a train. To remedy that condition, George Westinghouse invented the quick action triple valve in 1887. It automatically vents air from the brake pipe locally on each car, which applies the brakes more quickly.

Famous quotes containing the words quick, action and/or triple:
“People need to be made more aware of the need to work at learning how to live because life is so quick and sometimes it goes away too quickly.”
—Andy Warhol (1928–1987)
“To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.”
—Max J. Friedländer (1867–1958)
“And we fairies, that do run
By the triple Hecate’s team
From the presence of the sun,
Following darkness like a dream,
Now are frolic. Not a mouse
Shall disturb this hallowed house.”
—William Shakespeare (1564–1616)
