OPERATION ENVIRONMENT FOR NORTH AMERICAN FREIGHT TRAIN WHEELS DURING SPEED AND SLACK CONTROL BRAKING

This paper reports investigation into the intensity, degree and duration of train brake applications used to control train speed and slack action of contemporary North American freight trains during grade and power braking operations. Normal braking is unlikely to produce tread temperatures exceeding 600 deg F on either undulating terrain or on long and heavy grades.
