Railway Cleaning TRIZ Cases
- Rail Surface Laser Cleaning for Moving Contaminant Ablation
Pulsed laser spots ablate leaf residue, oil, and ice from rails at train speed while preserving traction and electrical contact.
- Railroad Sweeper Assembly With Rotatable Debris Conveyance
Rotatable sweeper, debris-removal, and conveyor components lift and transport rail debris for less manual track cleaning.
- Rail Web Sand Remover With Angled Caliper Arms
Angled caliper arms engage the rail web to clear accumulated sand deposits that surface plows miss.
- Rail Adhesion Control System Airflow Clog Detection
Adhesion control system detects nozzle clogs by comparing baseline and secondary airflow rates, preventing air consumption inefficiencies.
- Particle Removing Arrangement for Electric Rail Using Vehicle Motion
A particle removing arrangement uses vehicle motion to generate directed airflow that clears debris from the upper contact surface of an electric rail.
- Rail Vehicle Track Clearer Aerodynamic Guide Plates
Vertical guide plates deflect air streams laterally at clearing blade free ends, reducing pressure fluctuations without adding blade complexity.
