Abstract (en)
[origin: WO2019098925A1] The disclosure relates to railway switch mechanism (100) comprising a first switch blade (141) and/or first switch frog rail segment (143) that is vertically displaceable by means of a first displacement mechanism (200a, 200b) in order to establish a vertical switch movement of the first switch blade (141) and/or first switch frog rail segment (143) between an upper and lower switch state; and a second switch blade (142) and/or second switch frog rail segment (144) that is vertically displaceable by means of a second displacement mechanism (201a, 201b) in order to establish a vertical switch movement of the second switch blade (142) and/or second switch frog rail segment (144) between an upper and lower switch state. The disclosure also relates to a corresponding method for operating such a railway switch mechanism. Figure 5b
