Risk-informed sustainable asset management of railway tracks

Railway track infrastructure asset management is a challenging problem with added values on safety, society and environment. With railways serving as key sustainable mode of transportation for passengers freight, the industry facing an increasing demand to expand its capacity, availability speed, resulting in faster deterioration ageing railway infrastructure. Given constrained maintenance budgets environmental challenges posed by climate change, managers have identify economically environmentally justifiable strategies without compromising safety. To this end, paper proposes risk-informed approach arrive at while considering associated costs impacts train operation (environmental emissions risk derailments). Monte Carlo simulation employed address data uncertainties quality data, benefits operation. The proposed successfully applied heavy-haul lines Sweden Australia compare some alternative one.
