1 Preface Due to the low clearance of the tunnel and the narrow cross-sectional space at the locating point where the contact line locates, the research on the anti-elevation locator has plagued the development of electrification acceleration in the tunnel. At present, there are no anti-lift measures for the positioning of contact lines in the tunnel. As shown in FIG. 1, a hard
