    Author : Erik Nordlund; [2023]
    Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. READ MORE
