Short-pitch rail corrugation is prevalent on metro tracks with high-elastic fasteners and is closely linked to rolling noise. Field measurements show that the in situ pass-by noise reaches its maximum in the 600 Hz–1 kHz range.

This paper investigates dynamic instantaneous‐integration event‐triggered control for networked non‐linear rail vehicle suspension systems over the train communication network (TCN). The primary goal is to ensure the desired suspension performance while efficiently utilizing the train communication network (TCN) resources.

ABSTRACT Decarbonizing the intercity rail in sub‐Saharan Africa requires the use of energy architectures that go beyond traditional grid reliance at the expense of traction performance. This paper introduces a novel photovoltaic (PV)‐assisted hybrid traction topology for a 42 km Pretoria–Sandton rail corridor in South Africa, where between‐rail PV ...

Experimental Study on Spatial‐Position Effects of Subway Vibrations on Adjacent Tunnels
The effects of subway‐induced vibrations on surrounding structures are a critical issue in urban underground engineering, as they directly affect the structural stability and integrity of tunnels and nearby infrastructure. Existing research has mainly focused on the vibration responses of single tunnels, surrounding soils, or adjacent buildings, with ...
