  • Publication number: 20260160026
    Abstract: An angled guide plate for fastening rails for rail vehicles to a tie using a tension spring that can be supported on the angled guide plate includes at least one support face, in particular a support shoulder, formed on a top side of the angled guide plate, for supporting the tension spring, a rail-side contact face for a rail foot of the rail, and an underside, on the opposite side from the top side, for supporting the angled guide plate on the tie. Formed on the underside is a rib which can be received movably in a groove formed in the tie, wherein a guide face extending at an acute angle to the rail-side contact face is provided such that, as a result of the rib moving in the groove, an adjustment of the rail-side contact face with a direction component extending perpendicularly to the contact face can be effected.

  • Publication number: 20260125855
    Abstract: A tension spring for holding down a track body element, such as a rail foot of a rail, including a U-shaped main section which has a U-bend, a first leg arranged on one side of the U-bend and a second leg arranged on the other side of the U-bend, wherein a hook-shaped inwardly bent holding section which can be braced against a hold-down device is formed on the first leg and an end section bent towards or away from the holding section is formed on the second leg, wherein the U-bend forms a torsion section so that a hold-down force can be applied to the track body element via the bent end section.
