## Abstract

Railway wheel wear poses major safety and maintenance challenges, yet accurate predictive models are limited by a lack of synchronized dynamic and wear data from scaled systems. This article presents an integrated methodology to generate a correlative dataset of dynamic parameters and wear progression on the wheels of a 1:20 scale railway system. The experimental approach combines synchronized multisensor data acquisition with sequential microscopic imaging under controlled operating conditions, specifically during braking maneuvers at track transitions. The resulting publicly available dataset enables direct analysis of how operational factors influence physical degradation.
