Mutual Energy has been recognised for effective asset management of critical infrastructure by achieving ISO 55001 certification.
Rail grinding is used to restore the track head profile and remove corrugations. Such grinding extends the rail life, improves the ride quality of trains, and reduces noise. It also eliminates small cracks that might otherwise propagate to become rail breaks. Furthermore, the improved rail surface reduces rolling resistance to train wheels, so there are energy-saving benefits.
However grinding is expensive and time-consuming, requiring extensive track access during ‘engineering hours’, the grinding process itself can create risks, different curvatures of track result in different wear patterns and rates, and there are single/multi-pass options for the grinding method that have different effects. In this organization, rail grinding had usually been done reactively, as a response to track inspections identifying defects, drivers reporting poor rides, or railway neighbors complaining of the noise. On average this was being encountered after about 30 MGT of traffic. By the time the deterioration has become so evident, the grinding also requires multiple passes to remove a significant amount of the railhead to eradicate the defects. A more proactive approach, removing the defects in earlier stages of development, can be achieved with fewer passes of the grinder. However, the grinding is currently a purchased service from a specialist contractor, with complex and costly logistics for mobilization and usage. So more frequent grinding would be expensive and difficult to organize.
The study sought to determine the optimal rail grinding strategy for 300m, 600m and 900m radius curved track sections. These represent very different wear rates, compounded by differential train loading (passenger numbers and train frequencies) on different sections of the lines. The current regime involves hire of the rail grinding machine and re-profiling 300m and 600m radius sections after 30 Million Gross Tons (MGT) of traffic running over them.
This case involved a small team comprising of maintenance and operations personnel, with some consultation to procurement and customer service departments. It needed just half a day to build the ‘base case’ scenario, including the potential risk patterns for the variety of failure modes, the various defect and failure costs and consequences, the grinding costs, and how these increase with the amount of damage that needs to be removed.
This was achieved using the SALVO Process storyboard for evaluating and optimizing preventive maintenance, and DST Maintenance Evaluator™ to model the risks and calculate the optimal life cycle strategy. The study, including testing for sensitivity to the many uncertain assumptions, revealed that the business case for changing the grinding intervals was robust. In fact, the analysis demonstrated that it was not even worthwhile to collect ’better’ data since the optimal timings were unaffected across the min/max extreme ranges of credible values for deterioration rates, failure risks, event consequences, etc. Finally, the SALVO Process decision-recording stage ensured the documentation of all assumptions, scenarios explored, uncertainties, sensitivity analysis, and implications for alternative strategies providing a clear audit trail for why this rail grinding strategy is optimal.
This study used DST Maintenance Evaluator™ software to perform the complex reliability, risk, and financial ’what if?’ calculations. This tool was developed as part of the international SALVO project to support the analysis and optimization of preventive maintenance strategies. Like other modules in the DST Asset Strategy Evaluator™ suite, the tool provides:
The study revealed the optimal strategy for proactive rail grinding should be both track radius and train loading-dependent. For 300m radius track the optimal time to regrind is every 9 MGT of traffic, for the 600m radii the optimum is 17 MGT and for the 900m radius track, the lower wear rates shift the optimum out to 25 MGT. This selective and optimized strategy makes £15-25k/section/year net savings in total costs, risks and performance impact. So the study revealed the optimal approach for a program of selective sectional grinding for each route. Combined with similar studies for other routes and track loading rates, the analysis also provided the business case for procuring an in-house grinding machine.
