Train Inspection. When a train is made up at a terminal, the air hoseshould all be coupled and the angle cocks all opened except the one at the rearend of the last car. The brake pipe should then be charged to about 40 pounds,in order that the inspector may examine for leaks. When the brake pipe hasbeen fully charged, the engineer should apply the brake by making a lightreduction in the brake pipe, which should then be followed by a full-serviceapplication. He should note the time required in making these reductions,in order to be assured that all pistons are moved past the leakage groove whenthe train is out upon the road. The engineer, after making the full reduction,should leave his brake valve in lap position until the inspector has examinedthe brake under every car. It should be the duty of the engineer to see thatthe brake equipment on the locomotive is in proper working AIR BRAKES 169 Running Test. In passenger service, when a locomotive has been changedor a train made up, the engineer should mak(^ a running test within a mile ofthe station, as follows: A brake-pipe r(ulu(;tion of about 5 pounds should bemade. If the brakes arc felt to be applying and the time of the discharge isproportional to the numl^er of cars in the train, the engineer will conclude thatthe brake is in j)roper working order. It is well, also, to make this test onapproaching hazardous places. Sendee Applieations. In making a service application of the brakes, thefirst reduction should be about 5 j)Ounds on a train of cars 30 or less, and about7 pounds on a train exceeding 30 cars. This will insure the travel of all pistonsbeyond the leakage groove. Subsequent reductions of from two to three poundscan be made to increase the braking power, if des
