Retrofit Solutions

Tailored strategies for different operational needs.

Plan A

Pure Electric Shunter

For shunting yards and short-distance transport. Zero emissions, low noise.

  • Replace diesel engine with large capacity ESS
  • Ideal for stop-and-go operations
Plan B

Hybrid Mainline

For long-distance heavy haul. Diesel Range Extender + Battery Peak Shaving.

  • Downsize diesel engine + Add Power Battery
  • Regenerative braking recovers >20% energy

Core Technology

High power systems for heavy rail loads.

High Power EDS

Megawatt-class traction motors and controllers.

  • • High torque density
  • • Liquid cooling system

High C-rate ESS

Designed to absorb massive regenerative braking energy.

  • • 3C+ Charge/Discharge
  • • Extreme safety design

Energy Recovery

Capture kinetic energy on long descents.

  • • >20% Energy Recovery
  • • Reduced brake wear
