Definitions

  • FIG. 1 is a plan view of a railroad switch connected to a switching machine according to the invention
  • Each detector bar follower 64 A, 64 B has a body 71 with an elongated, diamond shape overall with two acute-angle corners and two obtuse-angle corners.
  • Each detector bar follower 64 A, 64 B further includes a switch arm 80 protruding from a top surface of the body 71 and extending substantially horizontally away from the follower part 76 .
  • the switch arm 80 has a free end 82 opposite the body 71 with a roller defining the contact surface of the detector bar follower 64 A, 64 B with the respective switch device 70 when the detector bar follower 64 A, 64 B it in its proximal position.
