Data‐driven maintenance planning and scheduling based on predicted railway track condition
Quality and Reliability Engineering International, 2022 Timely planning and scheduling of railway infrastructure maintenance interventions are crucial for increased safety, improved availability, and reduced cost. We propose a data‐driven decision‐support framework integrating track condition predictions with

Transportation Infrastructure Geotechnology, 2022 The faster and heavier trains in modern railway traffic are getting popularity in the public transportation authorities of many countries. Such trains cause higher stresses and excessive deformations in the ballasted railway track substructure under ...

Railway track design & degradation [PDF]
MATEC Web of Conferences, 2018 The long-term behaviour of railway track has attracted increasing attention in recent years. Improvements in long-term structural performance reduce demands for maintenance and increase the continuous availability of railway lines. The focus of this paper is on the prediction of the sensitivity of a track design to long-term deterioration in terms of ...
