An overlap section may, even though locked, be swung away from a conflicting route to provide a full-length overlap (source: INESS) The swinging overlap typically contains a facing point (de-DE: Ruderweiche). This implies that <ol> <li>there are two possible overlaps associated with the closed exit signal and</li> <li>the signaller can swing the overlap between left and right (normal and reverse).</li> </ol> The swinging overlap must point to two limiting train detectors. National rules and regulations govern when and how the facing point(s) can be thrown.
