The Straight Air Brake
The first form of the air brake consisted of an air pump, a main reservoir (pressure vessel), and an engineer's valve on the locomotive, and of a train pipe and brake cylinder on each car. One problem with this first form of the air brake was that braking was applied to the first cars in a train much sooner than to the rear cars, resulting in shocks and damages when the rear cars bunted against the cars ahead of them.
The main objection, however, was that it was not an automatic brake, i.e. even a minor mishap like a broken coupling left the entire train without any brake power at all.

Famous quotes containing the words straight and/or air:
“Columbus has sailed westward of these isles by the mariner’s compass, but neither he nor his successors have found them. We are no nearer than Plato was. The earnest seeker and hopeful discoverer of this New World always haunts the outskirts of his time, and walks through the densest crowd uninterrupted, and, as it were, in a straight line.”
—Henry David Thoreau (1817–1862)
“Hast not thy share? On winged feet,
Lo! it rushes thee to meet;
And all that Nature made thy own,
Floating in air or pent in stone,
Will rive the hills and swim the sea,
And, like thy shadow, follow thee.”
—Ralph Waldo Emerson (1803–1882)
