Fastening systems are used to fasten the steel rails to the railway sleepers and include components such as rail tie plate, spike, clip, rail anchor, fasteners, screws and bolts. These systems play a critical role in ensuring the safety of the railway track and vehicles while absorbing noise and shock and improving comfort for passengers.

Features considered when choosing a fastening system include:

  • High shock absorption capacity
  • Good insulation properties
  • Clamping force offered
  • Ease of operation
  • Fewer spare parts
