Physical Impact
Air brakes were a turning point to the railroad industry. The physical impact was that air brakes improved cost and maintenance. Not as many resources were spent on re-railing trains and wreck cleanup. Additionally parts on the train cars did not need to be replaced as soon like the wheels because when the brakes were tightened before air brakes, the wheels locked up and got flat spots on the wheel tread. Air brake parts are expensive but save money over time.
“Stephenson taught us how to move a railway train; Westinghouse taught us how to control its movements, and he made modern railway traffic possible.” Arthur Warren, March 6, 1904. The New York Times.
