D n IF A MODERN SIX CAR PASSENGER TRAIN WEIGHS n 1,500,000 POUNDS AND ATTAINS A SPEED OF 60 MILES n PER HOUR, IT HAS ACCUMULATED OVER ONE HUN- n DRED AND EIGHTY MILLION FOOT POUNDS OF EN- D ERGY TENDING TO KEEP THAT TRAIN IN MOTION. n n INERTIA IS WHAT THE AIR BRAKE IS UP AGAINST. D THE CONTROL OF INERTIA OR THE ENERGY OF MOV- n ING TRAINS WAS A MAN'S JOB IN 1870, WHEN AIR n BRAKES WERE FIRST APPLIED. TODAY—45 YEARS n LATER—THIS PROBLEM—WITH TRANSPORTATION IT- n SELF—HAS GROWN TO GIANT PROPORTIONS. n n WHAT IS THE ANSWER? D n MODERN BRAKES CONTROL MODERN TRAINS MORE PERFECTLY AND WITH GREATER SAFETY AND ECON- n OMY THAN EVER BEFORE IN THE HISTORY OF THE D ART. n n IF NECESSITY IS THE MOTHER OF INVENTION, n THEN INERTIA IS THE FATHER OF THE AIR BRAKE. n n n D D Suggested by the D D D Westinghouse Traction Brake Company a a a Works: Wilmerding, Pennsylvania D Building NEW YORK: City Investing Building D PITTSBURGH: Westinghouse D CHICAGO: Railway Exchange Building ST.
