TrackPan GRP Pollution Control System

The Cairn Cross TrackPan GRP System is an innovative pollution control solution designed specifically for railway maintenance environments.

The system captures and manages water runoff during rail vehicle cleaning and maintenance activities, preventing pollutants and contaminants from entering the surrounding environment.

The integrated raised GRP walkway provides a safe, level, anti-slip working surface for maintenance staff, while the drainage pan beneath collects and channels water into existing drainage systems.

Key benefits of the TrackPan system include:

  • Effective containment of contaminated water runoff
  • Improved environmental compliance
  • Safer access for maintenance teams
  • Reduced risk of pollution incidents
  • Integration with existing rail infrastructure
  • Durable GRP construction suitable for demanding depot environments
