Power of Air Brakes.
Some idea of the power of an air brake may be gained from the following facts: It takes a powerful locomotive drawing a train of ten passenger cars a distance of about five miles to reach a speed of 60 miles an hour on a straight and level track. The brakes will stop the same train from a speed of 60 miles an hour In TOO feet Roughly, it may be stated that a train may be stopped by the brakes in about 3 percent. of the distance that must be covered to give it its speed.—Science Conspectus.
