Abstract
A train control and monitoring system detects operating errors in controlled devices in each car and disables a car propulsion system if an error is detected. Operator reset is employed to reactivate a car, but operator reset control is disabled if a limit error count is reached and in that event only a supervisor reset can reactivate the car. When a car performs with good behavior through a power/brake cycle, the error count is decremented by one count.
