This report represents the user manual documentation for the Lateral/Vertical Computer program. The program described simulates the dynamic responses of a freight car truck with flanged wheels. Emphasis is on the wheel-rail interaction. The program can be used to study freight car derailments due to wheel climb. Also, high speed hunting can be studied. The program model describes a single freight car truck with a suspended mass on top. L/V (Lateral force/Vertical force, a derailment tendency coefficient) is part of its output.
