This makes it possible, on the one hand, to check whether heating of the switch is still necessary due to the ambient temperature and, on the other hand, how much degrees the temperature temperature of the stock rails has been increased by the respective heating elements or is.
- the sensor arrangement expediently has a sensor for monitoring activation of the heating elements.
- This sensor is, for example, a gas flow sensor connected to a gas supply line of the heating elements designed as gas burners.

- the method for monitoring the functionality of a heatable switch of a rail network provides that in a first step, the switch is heated.
- a stock rail of the switch is heated to ⁇ special.
- Legally advantageous ⁇ the area of the stock rails is heated, which is provided for establishment of a switch blade of the switch.

In contrast, a functionality of the point heater is assumed in particular at a temperature value above or equal to the threshold value.
- the threshold is either fixed or adapted to current requirements. For example, the threshold is 0 ° C.
- the temperature of the switch Due to the determination of the temperature of the switch can be deduced on the functionality of the point heater, the temperature is monitored directly.

Rather, this will be automatic adapted to different environmental conditions and operating situa ⁇ tions of the switch. Therefore, any further parameterization of the threshold value or the detection or determination of a reference temperature can be dispensed with.
- Example ⁇ as both stock rails, are monitored and in each case a separate threshold value is used, the respective threshold values by means of the mean value of the temperature is created that were created from the detected at this same rail temperatures. In each case, a security value is deducted from the mean, which is the same or different for both rails.

- the same threshold herangezo ⁇ gene which is gebil- det from the average of all temperature values for all temperature values.
- a security value of 0 ° C is conceivable, as long as the temperature is detected at a distance from all heating elements.
- the temperature value created by means of this temperature contributes to the formation of the threshold value (s), but is not compared with the respective threshold value.
- this temperature value contributes to the determination of the respective threshold value.
- this temperature value can serve for the decision as to whether heating of the switch is required.
- the backup ⁇ set value in particular to a positive value.
- the result of the function test on egg ⁇ ne maintenance control center or a centralized track control station is transmitted.
- the result or the value of the function check are either the determined temperature values or particularly preferably a binary value. This indicates, for example, whether all the determined temperature values are above or below the threshold value and whether it is thus possible to operate the points in winter-proof operation. Alternatively, it is transmitted as a binary value, whether the winter safe operation of the switch is possible, so whether the point heater works correctly.
