The impact of axle loads on rail infrastructure maintenance costs
Abstract: In this paper we estimate the impact of axle loads on rail
infrastructure maintenance costs in Sweden. The results are contrasted to
the cost impact of ton density, a common measure in the literature on rail
infrastructure costs. We find non-linear cost elasticities with respect to
a ton per axle density measure, with an estimate at the sample median that
is larger than the corresponding estimate for ton density. The results are
relevant for the setting of track access charges in Europe, considering
that the econometric results in this paper give support to the engineering
perspective - that is, axle loads are important to consider when estimating
the damage caused by traffic.
