The invention relates to a rail vehicle (1) having at least one vehicle antenna (25) of a train safety system directed toward the track (30). To increase resistance to interference, the rail vehicle according to the invention is designed such that the body (5a, 5b, 5c) of the rail vehicle (1) and an axle (7a) arranged in the region of an end of the rail vehicle (1) are electrically connected by means of a capacitive connection and the at least one vehicle antenna (25) is arranged at a greater distance from the end of the rail vehicle (1) than the axle (7a) that is electrically connected to the body (5a, 5b, 5c).

The invention relates to a high voltage device for a vehicle, which at least during driving operation is supplied with electric energy from a power system (20) providing a high voltage, having at least one high voltage component (24), which by means of a main power switching unit (30) is electrically connectable to the power system (20), and a grounding switching device (36) having at least one switching means (38). In order to increase personal safety during work on the high voltage device in a constructively simple manner, it is proposed that the high voltage component (24) have at least one receiving region (46) in which the switching means (38) is accommodated - at least in a grounding position that grounds at least one active section (35) of the high voltage component (24).

The invention relates to an electric rail vehicle (1) having a first and a second vehicle drive unit (2, 5) which have, at their ends facing one another, a first and a second current collector trolley (4, 9) whose current collector (4a, 9a) is connected to a common power supply line (16) of the rail vehicle (1). In order to develop further such a rail vehicle in such a way that in virtually any configuration it satisfies the safety requirements with respect to electrical faults, according to the invention at least one central vehicle unit (11) with a high voltage system which is connected to a central section (17) of the common power supply line (16) is arranged between the current collector trolleys (4, 9); in the course of the common power supply line (16) a first section main switch (18) is arranged in series with a first end section main switch (20) at a first end of the central section (17) of said power supply line (16), and a second section main switch (19) is arranged in series with a second end section main switch (26) at a second end of the central section (17), and the current collector (4a) of the first current collector trolley (4) is connected to the connecting point (24) of the first section main switch (18) and of the first end section main switch (20), and the current collector (9a) of the second current collector trolley (9) is connected to the connecting point (28) of the second section main switch (19) and of the second end section main switch (26). The invention also relates to a method for operating this rail vehicle.
