Inspection and maintenance activities are essential to preserving safety and cost-
effectiveness in railways. However, the stochastic nature of railway defect occurrence is …

This article proposes a model for the risk-based scheduling of predictive maintenance
activities on a railway line to intervene when a track segment has reached a certain state of …

Rail network velocity is defined as system-wide average speed of line-haul movement
between terminals. To accommodate increased service demand and load on rail networks …

National railways are typically large and complex systems. Their network infrastructure
usually includes extended track sections, bridges, stations and other supporting assets. In …

Railway big data technologies are transforming the existing track inspection and
maintenance policy deployed for railroads in North America. This paper develops a data …

In order to optimally schedule railway track maintenance operations, it is essential to
accurately estimate future track conditions. This study proposes a railway track geometry …

Conventional planning of maintenance and renewal work for railway track is based on
heuristics and simple scheduling. The railway industry is now collecting a large amount of …

Railway track maintenance and renewal are vital for railway safety, train punctuality, and
travel comfort. Therefore, having cost-effective maintenance is critical in managing railway …

Developing optimal rail renewal and maintenance planning that minimizes long-term costs
and risks of failure is of paramount importance for railroad industry. However, intrinsic …

An optimization-based maintenance scheduling framework is an essential tool to plan the
necessary investment to maintain the required performance of a railway line. In the present …
