Aerodynamic noise reduction methods for key components of high-speed train pantographs

Puntos clave

• Aerodynamic noise reduction methods substantially lower sound levels around pantographs, enhancing overall passenger experience.
• Noise levels were decreased by up to 12 decibels with modified pantograph designs during trials.
• Assessment using sound measurement techniques highlighted the significance of aerodynamic adjustments in design.
• Highlighting the need for further studies to validate findings across various operational conditions.
