Another concerning issue is the level of (or the ripple on) the earth magnetic field. Calculations for each situation (location along the line) should give an answer as to whether the reduction of the magnetic field emission (related to the emission of a “standard” catenary system) of a certain mentioned mitigating system will be sufficient enough. Concerning mitigating measures at the equipment side, one can think of different shielding methods, such as Helmholtz cages.

Example of mitigating alternative designs of the power supply system are sectioning of the catenary system, the use of capacitors and/or batteries in the trams or a trolley system. For example, only the use of mitigating measures, for specific locations. Major goal is to limit the mitigations along the line to the absolute minimum possible.

Also mitigating measures for the affected equipment have been studied, although this usually is not the preferred method. Mitigation methods, such as alternative designs of the power supply system or modifications of rolling stock have, been studied.

In order to assess possible problems as early as possible, simulation software has been developed, taking in to account the effects of stray currents. This is hampering the introduction of light rail systems especially in the neighbourhood of hospitals and university complexes, where quite often the need for a good transport system is high. magnetic fields such as electron microscopes, NMR spectrometers and MRI scanners is growing, at the same time the immunity levels of this type of equipment are decreasing. Also at the moment the number of systems which can be influenced by d.c. In order to provide high quality fast transport, power demand is increasing. systems rarely led to EMC issues, as the number of systems susceptible to low frequency E.M. The last few years in The Netherlands there has been a growing interest in light rail systems in order to reduce congestion in major cities.
