| Abstract(in English) | In railway signalling systems, track circuits based on an electrical shunting principle are used to detect the presence of a train within a particular track section. An increase of contact resistances between rail and wheel makes the detection difficult. Therefore, it is important to quantitatively estimate the contact resistances in order to detect trains exactly. The contact resistances may behave like semiconductors, but their semiconductor characteristics have not been sufficiently studied for the quantitative estimation. In this paper, we propose electrical-circuit models for the semiconductor characteristics, and show their performance based on comparison with measurement data. |
