Abstract

In this paper we analyse the effect of activated magnetic track brakes on the ferromagnetic environment and the so-called magnetic signatures, which are location dependent variations of the earth magnetic field along railway tracks. Such magnetic signatures can be used solely or in combination with other track features for train localization. For this application it is of fundamental importance to understand the permanent and volatile influencing factors that may change the magnetic track signatures. As implied by the name, magnetic track brakes might have such an influence. Therefore, we evaluate the characteristics and persistency of this influence based on a worldwide unique measurement campaign.
