“…The first category concentrates on railway component degradation modeling and maintenance interval determination for a single component or a single type of maintenance activity. Ballast tamping is referred to as a preventive maintenance activity in a number of studies (Zhao et al 2006;Andrade and Teixeira 2011;Caetano and Teixeira 2016;Vale et al 2012). A life-cycle cost approach for ballast tamping and renewal is presented in Zhao et al (2006).…”

Maintenance planning for busy railway systems is challenging since there is growing pressure on increasing operation time, which reduces the infrastructure-accessible time for maintenance. This paper proposes an optimization model that is aimed at finding the best maintenance schedule for multiple components in a railway track to minimize the total cost in the planning horizon. One distinct and practical feature of the model is that the track accessible time for maintenance is limited. We formulate all relevant costs in the component's life-cycle, including maintenance cost, fixed track-closure (possession) cost, social-economic cost related to the effects of maintenance time on the train operation, and service-life shortening cost due to the shifting of activities. Generally, it is beneficial to cluster and maintain several components in a single possession as this helps reduce the cost by occupying the track only once. However, the decision must depend on the available possession time. A sensitivity analysis is performed to highlight the effects of available possession time on the number of required possessions as well as the total cost incurred.

“…Recently, research on railway-specific M&R actions appeared. One branch concentrated on optimizing synchronized M&R actions on multiple track components, considering track degradation and operational aspects (Andrade and Teixeira, 2011;Caetano and Teixeira, 2013, 2016Dao et al, 2018). Track degradation was also considered by Lee et al (2018) and Peralta et al (2018), in tandem with track quality constraints, and safety and resource constraints.…”

Multiobjective model for optimizing railway infrastructure asset renewal A multiobjective model for managing railway infrastructure asset renewal is presented. The model aims at optimizing three objectives, while respecting operational constraints: leveling investment throughout multiple years, minimizing total cost, minimizing work start postponements. Its output is an optimized intervention schedule. The model is based on a case-study from a Portuguese infrastructure management company, who specified the objectives and constraints, and reflects management practice on railway infrastructure. Results show that investment leveling greatly influences the other objectives and that total cost fluctuations may range from insignificant to important, depending on infrastructure condition. The results structure is argued to be general and suggests a practical methodology for analyzing trade-offs and selecting a solution for implementation.

“…ballast, sleeper, and overhead line, or a single type of activity where the optimal maintenance or renewal intervals for the component are identified (Zhao et al 2006; Andrade and Teixeira 2011;Vale et al 2012;Zhao et al 2007;Zorita A. L. et al 2010;Santos and Teixeira 2012). Others scholars investigate a single track line with different types of component to determine the optimal maintenance schedule to be applied to the line (Budai et al 2006;Pouryousef et al 2010;Pargar et al 2017;Caetano and Teixeira 2013;Caetano and Teixeira 2015;Zhao et al 2009;Dao et al 2018;Higgins 1998;Burkhalter et al 2018).…”

The pressing necessity to renew infrastructure assets in developed railway systems leads to an increased number of activities to be scheduled annually. Scheduling of renewal activities for a railway network is a critical task since these activities often require a significant amount of time and create a capacity conflict in operation scheduling. This paper discusses economic and technological aspects, opportunities, and constraints in the renewals of multiple rail infrastructure components at several locations in a railway network. We address and model a challenging situation that there are interrelationships between different track lines, and thus, possession of a track line can have impacts on the other track lines and prevent renewal works on them. A mathematical formulation for the railway infrastructure renewal scheduling problem in the network context is presented to minimize the total renewal and unavailability costs. A method based on a triple-prioritization rule and an optimal sharing of renewal times allocated for different types of rail infrastructure components in a possession is proposed to solve the problem. The method is applied to a real case of a regional railway network in Northern Netherlands and it is shown that up to 13% of total costs can be saved compared to the current scheduling practice.
