Pantograph Wear & Performance System

Apply precise longitudinal, horizontal and vertical loading to railway pantograph specimens to replicate the highly complex and dynamic pantograph-catenary (trolley wire) operating environment. This high fidelity simulator features multiple test modes, enabling manufacturers to study the complete operational dynamics of pantograph designs under a wide array of real-world scenarios.


  • Real-world pantograph scenarios
  • Off-line ratio
  • Resistance of contact
  • Contact force
  • Power Factor
  • Arcing time and intensity
  • Contact bar temperature
  • Real-time trolley wire and contact bar wear
  • HIL Suspension Studies
