Thick web switches and its advantages

Thick web switches


·        Thick web switches are an ideal solution for heavy haul/ passenger traffic lines as well as for high speed lines. The asymmetrical section in these switches offers a very high lateral rigidity, increasing the life of the switch. These can be supplied for partially or fully canted turnouts.

·        These switches are made from specific asymmetrical tongue rail sections, forged at the end to match standard rail sections. The transition from one section to the other lies mostly in the clamped area at the end of the switch. Thus welding becomes superfluous in the flexible area.
·        The length of the forging can be adjusted to the specific connecting system such as welding, insulated fishplate or emergency fishplate. In order to reduce the setting forces and to influence the elastic strength of the switch, the base of the switch rail is milled in the flexible area.
·        Advantages:
Ø Reduces jerks
Ø Considerably lengthens life span
Ø  Ensures minimum distortion under moving load through high lateral rigidity
Ø  Leaves no welded joint in the complete, non-clamped switch area
