Abstract: A student training system for a vehicle system is provided. The student training system has a primary computer that displays a first GUI having a first case study command button associated with a first case study. The first case study is a training assignment associated with a first operational problem in the vehicle system. The primary computer displays a second GUI having text that describes the first operational problem, and a start case study command button. The primary computer sends a first code to the intermediate microprocessor when the start case study command button is selected. The intermediate microprocessor generates a control signal in response to the code to induce a controllable switch to electrically de-couple a first device from the controller to induce the vehicle system to have the first operational problem.
