Fastening System used in harsh environmental conditions

High temperatures can cause rail expansion, while low temperatures can lead to contraction and brittleness.

Fastening systems must accommodate thermal movements without losing grip or stability.

Water can cause corrosion of metal components and degradation of insulating materials.

Poor drainage can lead to waterlogging, increasing stress on the track.

Saltwater, chemicals, and pollutants can accelerate corrosion of fastening components.

Coastal areas and industrial zones are particularly prone to this issue.

Prolonged exposure to sunlight can degrade rubber and plastic components (e.g., rail pads, insulators).

High-stress conditions can accelerate wear and tear on fastening systems.
