The Quasi-Static Lateral Train Stability Model simulates a train on a given track in a pushing or braking mode. The program calculates lateral forces at the bolster centers and coupler pins, a quasi-static equilibrium position, the coupler angles and the moments due to alignemt control. Derailment, wheel climbing, rail overturning, train makeup, draft gear wear, track configuration and curve negotiation forces may be calculated. As a design tool, the program can be used to evaluate the effect or carbody overhang, maximum bolster lateral displacement from the centerline of the track, optimum bolster spacing and coupler length.
