The E-T Air-Brake Pocket-Book valve, and the distributing valve, and indirectly, through the automatic brake-valve to the excess-pressure governor top. The feed valve is adjusted to supply 70 pounds of pressure in all branches of service except the High-Speed Brake, to the feed-valve pipe (brown), which delivers this air to the automatic brake-valve, and through a small connecting pipe to the regulatingspring case of the excess-pressure governor top. With the automatic brake-valve in running position, as shown, or in holding position, the feed-valve pipe air passes through the rotary valve to a branch of the brake pipe (yellow), at the same pressure, and from which there are two connecting pipes, one leading to the small duplex gauge on which the brake-pipe pressure is registered by the black hand, and the other one to the cutout cock in the by-pass arrangement used in charging the air equipment of a "dead" engine, this branch pipe teeing into the main brake pipe that leads to all triple valves of the train, and from which the air passes through the large strainer-tee, and branch pipe, to the distributing valve. The reducing valve regulates the air supply to the reducing-valve pipe (lavender), at 45-pounds pressure which feeds to the independent brake-valve, and has a branch connecting to the signal line strainer-and-check; beyond this fitting the same amount of pressure ensues, but it is then called the signal-line pressure (purple).
