Underhåll i egen regi?: metod och databehov för en utvärdering av järnvägsunderhåll


Maintenance of the state-owned railway network in Sweden is currently tendered in competition. However, during 2016, the infrastructure manager Trafikverket (Swedish Transport Administration) was commissioned by the Swedish government to analyze and present appropriate measures to organize and produce rail maintenance in-house. This includes an investigation that is based on an inhouse production of maintenance in at least two geographically defined areas, with the aim to compare it with maintenance tendered in competition. This memorandum describes the method and data needs for an evaluation of whether in-house production is preferable to maintenance tendered in competition or not.

This type of evaluation should measure potential differences in socio-economic efficiency between the organizational alternatives. How in-house maintenance affects costs for production and administration should therefore be determined together with its impact on cost for delays. A challenge is to isolate the effect from differences in preconditions for the maintenance production, such as differences in infrastructure characteristics and in traffic. A comparison should for example consider economies of scale and economies of density as the size of maintenance areas and the traffic volume differs. This implies that key performance indicators such as cost per ton-km is not suitable in this case. An ideal comparison should also consider that possible savings (cost increases) can lead to losses (gains) in the long run, which means that the effects should be assessed over a longer period.
