The connections typically consist of several air hoses for controlling the air brake system, and an electrical cable for the control of the traction equipment.
The largest hose, located next to the coupler is the main air brake line or train line.
On these automobiles, the spoiler will actually tilt almost vertically under heavy braking to act as an air brake system.
These provided extra power in light winds, but acted as an effective air brake in strong winds.
While in this employment, the air brake was invented, and he became very interested in its development.
A traditional train air brake was optional, but all came with two compressors (one per engine) and a straight-air independent (locomotive) brake.
Serial braking is where a train descends a grade on the air brake alone.
He made an emergency application of the train vacuum brake and the locomotive air brake.
