Abstract
A rail vehicle contains a vehicle control system being connected to a drive enable device which controls drive components for the operation of the vehicle. The vehicle control system is connected to a high-voltage enable device which controls high-voltage components of the rail vehicle. The rail vehicle contains a locking device containing controllable switches. A first switch is interposed between the vehicle control system and the drive enable device so that the control of the drive components can be prevented when the first switch is open and executed when the first switch is closed. A second switch is interposed between the vehicle control system and the high-voltage enable device so that the control of the high-voltage components can be prevented when the second switch is open and executed when the second switch is closed. The locking device is connected to an enable device which closes the switches after an authentication.
