Comparison of Laser and Water Jet Technologies in Rail Cleaning

  1. Highest Effectiveness: Water jet technology offers the best performance in increasing the friction coefficient and reducing contamination. It can effectively remove all types of contaminants.
  2. Versatility: Unlike laser technology, which is less effective on oily contaminants, water jet technology can handle a wide range of contaminants, including heavy oils and organic materials, effectively.
  3. Safety: The risks associated with high-pressure water are lower compared to the potential hazards of laser beams. There is no risk of eye damage or skin burns, making handling safer.
  4. Proven Technology: Water jet technology is well-established and widely used. The necessary equipment and procedures for maintenance and operation are mature and reliable.
  5. Simple Safety Measures: While laser usage requires stringent safety precautions, the safety measures for water jet technology are easier to implement and do not require highly specialized protective measures. Measures like protective clothing and barriers are generally sufficient.
  6. Extensive Experience: Since water jet technology has been in use for a long time, there is extensive experience and knowledge about its optimal application and maintenance, further increasing efficiency and reliability.
Overall, water jet technology offers significant advantages over laser technology in terms of effectiveness, safety, and proven applications, despite the logistical challenges posed by high water consumption.
The graphic illustrates the differences between laser and water jet technology for rail cleaning. The strengths of the water jet are clearly visible.
  • Operation: Water Jet Technology scored higher due to its simplicity and well-established operation procedures.
  • Effectiveness: Water Jet Technology is significantly more effective in increasing friction coefficient and reducing contamination.
  • Maintenance: Both technologies require regular maintenance, but Water Jet Technology has a slight edge due to its maturity and established procedures.
  • Safety: Water Jet Technology is safer, with simpler safety measures compared to the stringent requirements for Laser Technology.
  • Logistics: Both technologies have logistical challenges

Comparison of Laser and Water Jet Technologies in Rail Cleaning

Laser Technology:

  • Operation: Pulsed Laser Ablation uses infrared lasers to vaporize contaminants and turn them into dust. A plasma plume is generated, which ablates the contamination.
  • Effectiveness: Laser technology offers moderate effectiveness. It shows good results on natural contaminants but is less efficient on oily contaminants.
  • Maintenance: Requires regular inspections and calibrations. Maintenance can be performed both on-site and in depots, but specialized equipment and expertise are needed.
  • Safety: Class 4 lasers require extensive safety measures to prevent eye damage and skin burns.
  • Logistics: The modular design allows flexible installations, but the technology is still in the optimization phase to achieve higher efficiency and lower energy consumption.

Water Jet Technology:

  • Operation: High-pressure water jet (300-750 bar) that removes contaminants from the rail head at speeds of up to 120 km/h. The water jet cleans the rail head and ensures a direct contact surface between the wheel and the rail.
  • Effectiveness: Water jet technology is the most effective in increasing the friction coefficient and reducing contamination. It works effectively on all types of contaminants, including oil, leaves, and general rail contaminants.
  • Maintenance: Regular inspections and maintenance are necessary, but they are well-established and can be efficiently performed.
  • Safety: Water consumption is low compared to traditional water jet cleaning methods, approximately one-tenth of the usual amount. The ConSus® technology is mature and can be operated with existing machines and infrastructure.
