- the safety-critical auxiliary gear 26a is electrically coupled to the train busbar 20.
- the safety-critical auxiliary equipment related 26a electrical energy across said Switzerlandsammeischiene 20, 22b, electric power is fed to the second from the power supply unit.
- a safety ⁇ measure can take place, such as a deceleration of
- Rail vehicle 2 (possibly to a standstill).
- the second power supply unit 22b also energy in the Switzerlandsammeischiene 20 a ⁇ fed when the first energy supply unit error ⁇ works freely 22a and the vehicle power supply 12 in the "normal mode” or in the "off-grid” mode is operated.
- each of the aforementioned switch 44 is opened, whereby the safety-critical auxiliary equipment are electrically decoupled from the first 26a Energyeinspei ⁇ sungsaku 22a and the first power supply unit 22a and the safetycritical see auxiliary operations 26a of the Switzerlandsammeischiene 20 are elec ⁇ electrically decoupled.
- an emergency braking is initiated, preferably by means of a friction brake of the rail vehicle 2 and, if necessary, using those electric brakes of the rail vehicle 2, the auxiliary equipment are electrically connected to ei ⁇ ner non-defective power supply unit of the electrical system 12th
- actuation of the switch 44 in the manner described above is only possible if a corresponding release was given by a vehicle driver before, for example, via a control element ei ⁇ nes cab of the rail vehicle 2.
