    Powszechne stosowanie przez r贸偶ne zarz膮dy kolejowe licznikowych system贸w stwierdzania niezaj臋to艣ci tor贸w uwidoczni艂o problematyk臋 odporno艣ci tych urz膮dze艅 na zaburzenia generowane przez tabor kolejowy. Innym aspektem zwi膮zanym z t膮 tematyk膮 jest r贸wnie偶 wyposa偶anie pojazd贸w szynowych w urz膮dzenia elektryczne i elektroniczne o rozbudowanej strukturze. Z do艣wiadczenia wielu zarz膮d贸w kolejowych wynika, 偶e nowoczesne pojazdy mog膮 powodowa膰 zak艂贸cenia w pracy licznik贸w osi. Z tego wzgl臋du od wielu lat trwaj膮 prace normalizacyjne na poziomie europejskim, maj膮ce na celu ujednolicenie i uproszczenie procedur zwi膮zanych z dopuszczaniem poszczeg贸lnych typ贸w taboru kolejowego do eksploatacji na europejskiej sieci kolejowej. Przedstawione w artykule przyk艂adowe wyniki bada艅 potwierdzaj膮 konieczno艣膰 wykonywania pomiar贸w zar贸wno w trakcji elektrycznej, jak i spalinowej, ze wzgl臋du na podobny charakter emisji i warto艣ci mierzonych poziom贸w. Wykonywanie pomiar贸w wp艂ywu p贸l magnetycznych emitowanych przez pojazdy trakcyjne jest istotnym sk艂adnikiem bada艅 kompatybilno艣ci elektromagnetycznej taboru poruszaj膮cego si臋 po torach kolejowych, wyposa偶onych w urz膮dzenia wykrywania obecno艣ci poci膮gu

    Axle counters are more and more often applied in train detection systems. The wheel sensor is a main part of each axle counter system. In parallel, more and more complex railway vehicles, especially traction ones, are a potential source of interferences influencing the operation of these train detection systems. It is the reason to verify the electromagnetic compatibility (EMC) between the signalling equipment, particularly train detection systems and new vehicles in the process of obtaining the permission for their exploitation. The measurement of interfering magnetic fields generated by vehicles is one of tests to be carried out. For the simplification and unification purpose of the applied interference test methods the EN 50238 standard and TS 50238-3 technical specification were developed. The specification defines unified testing procedures. However, it is necessary to verify if it may replace different testing methods used in particular European states. It is the goal of the European research project financed from the TEN-T network resources

    The widespread use of counter clear track reporting systems by various railway managements has highlighted the problem of the resistance of these devices to disturbances generated by rolling stock. Equipping rail vehicles with electrical and electronic devices featuring extensive structures is another aspect related to this topic. The experience of many railway managements shows that modern vehicles can cause disturbances in the operation of axle counters. For this reason, standardization work at European level, aiming to harmonize and simplify the procedures related to the authorization of individual types of rolling stock for operation on the European rail network, has been ongoing for many years. The study results presented in the article show the need to perform measurements for both electric and diesel tractions, due to the similar nature of emissions and measured levels. Impact measurement of magnetic fields emitted by traction vehicles is an important component of the electromagnetic compatibility tests of rolling stock moving on rail tracks equipped with train detection devices
