Definitions

  • the invention relates to a rail switch arrangement, with a rail switch and a heat exchanger arrangement for a heating system for heating the rail switch.
  • Rail switches or points are by definition track constructions for track evaluation and association.
  • Turnouts are incorporated in track-guided traffic to branch railways, to turn sideways or swerve, to allow overtaking, to bypass sections etc.
  • switches are track structures, the rail vehicles allow the transition from one track to another track without interruption. In this case, moving parts of a switch are moved back and forth, thus initiating a change of direction within tracks.
  • a tongue rail also called tongue for short
  • a stock rail also called Vignol rail
  • a variant of the sliding chair is common, which is not manufactured or executed in one piece.
  • the Gleitstuhlplatte for the management of a stock rail and a base plate for the attachment of a stock rail are made separately and then connected together.
