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:
“I fell her finger light
Laid pausefully upon life’s headlong train;—
The foot less prompt to meet the morning dew,
The heart less bounding at emotion new,
And hope, once crush’d, less quick to spring again.”
—Matthew Arnold (1822–1888)
“A thought which does not result in an action is nothing much, and an action which does not proceed from a thought is nothing at all.”
—Georges Bernanos (1888–1948)
“And DANTE searched the triple spheres,
Moulding nature at his will,
So shaped, so colored, swift or still,
And, sculptor-like, his large design
Etched on Alp and Apennine.”
—Ralph Waldo Emerson (1803–1882)
