High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system.

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This study proposes an NSGA‐II framework enhanced with struct‐based encoding for bi‐objective optimization of heavy‐haul railway vertical alignment (construction cost and energy consumption), which requires no preset vertical points of intersection (VPIs) and inherently meets most constraints.

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...

Introduction of variability in pantograph-catenary dynamic simulations [PDF]
, 2013 Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.
