ABSTRACT: This reference manual on lateral force characteristics of various types of draft gears and couplers under draft and buff loads during angling was developed as part of the Track-Train Dynamics Program. Data from these tests can be used in several TTD mathematical models, particularly the Lateral Train Stability Models. The dynamic interactions investigated are those produced by combinations of long and short cars, length of tangent between reverse curves, change in superelevation in spirals, and jackknifing tendencies for a variety of car combinations, track geometries and operating practices.
