Squat Detection of Railway Switches and Crossings Using Wavelets and Isolation Forest [PDF]
Sensors, 2022 Railway switches and crossings (S&Cs) are critical, high-value assets in railway networks. A single failure of such an asset could result in severe network disturbance and considerable economical losses. Squats are common rail surface defects of S&Cs and

Automated machine learning recognition to diagnose flood resilience of railway switches and crossings [PDF]
Scientific Reports, 2023 The increase in demand for railway transportation results in a significant need for higher train axle load and faster speed. Weak and sensitive trackforms such as railway switches and crossings (or called ‘turnout’) can suffer from such an increase in ...
