Sammanfattning:
The purpose of this paper is to describe an application of a systematic risk-based dependability approach to support the digitalisation of railway infrastructure maintenance. The overall research strategy is a single case study of the heating system in switches and crossings (S&C) at the Iron ore line and the Haparanda line in northern Sweden. The applied systematic dependability approach combines risk analysis of existing maintenance programmes and statistically based design of field experiments. The applied approach is valuable to systematize the digitalisation of existing railway infrastructure maintenance by supporting a more dynamic maintenance programme. This is achieved by the possibility to reverse engineer the logic of existing maintenance programmes, evaluate the applicability of these programmes, and deduct a new more effective and efficient maintenance programme to replace the former. The approach
supports a more dynamic maintenance programme based on best practices that facilitates the implementation of solutions based on digitalisation. The approach also supports the development of indicators, monitoring and continuous dependability
improvement. In addition, the approach supports an increased digitalisation of maintenance by achieving a more dynamic maintenance programme that are deducted from best practices and becomes more efficient, through improved maintenance, and
effective, through compliance with regulations.
