Preliminary study on effect relationship for the maintenance of railway

Published: 4 January 2016

Maintenance of our railways is important for them to continue to be an attractive means of transport, corresponding to both passengers and freight customers' expectations for reliability. In pace with the demands of sustainable travel and transport increases, the railway's position in society and more important. At the same time, we have in recent years seen the punctuality and regularity of rail services, which has resulted in the need to calculate the benefits of preventive maintenance.

Christer Stenström from the Luleå Railway Research Center (JVTC) at the University, together with Oskar Fröidh from KTH Railway Group and Traffic Authority, completed a feasibility study on effect relationship for track maintenance. The intention was to examine the availability and quality of data, to calculate the benefits of preventive maintenance.

- Effect relations for maintenance of the railway is an area in which there is strong reason to develop, says Christer. This enables assessment of where the railroad maintenance make the biggest difference, which increases cost effectiveness.

The project team has found a formulation demonstrating efficacy relationship.

- When an inspection is carried out in the railway, the probability of an inspection note somewhere between 0 and 100%. Addressed not note that there is a risk of failure, and consequently delays. Counting this together, a measure of the number to prevent delay by the train.
