Randomized trial assesses railway infrastructure conditions using onboard monitoring system, suggesting improved detection methods.

The central aim is to develop and validate an onboard monitoring system for assessing railway infrastructure conditions.
Development of a monitoring system using accelerometers on locomotives.
Real-time data acquisition, storage, and transmission under operational conditions.
Evaluation of defect detection methodologies: continuous time wavelet transform and time-domain autoencoder.
Both methods distinguished damaged from intact rail sections (p<0.05).
Severely damaged sections had higher damage indices compared to intact ones (RR=3.2, 95% CI 2.1-4.5, p=0.001).
The monitoring system proved robust for continuous condition assessment.

Bragança et al. (2026) studied this question.
