The use of alternative powertrain concepts in rail transport, e.g. battery and/or hydrogen trains, represent a technological solution for the decarbonisation of the transport sector. This is particularly true on route segments where electrification with overhead lines is economically unviable, so that diesel trains are the primary means of transport in today’s operations. However, with the introduction of novel propulsion concepts, new requirements arise for the operation and the components used in rolling stock. One important aspect is the corresponding maintenance to ensure reliable, safe and sustainable operation. In this context, the changes in required spare material supply as well as man hours, resulting from new system components such as batteries, fuel cells or hydrogen tanks, need to be analysed and subsequently compared to conventional power concepts. Ultimately, these results can be used in the system design to support, among other things, the development of a maintenance-friendly concepts.
As part of our team, you will be responsible for the following tasks:
- analysis of the state of the art of maintenance processes and activities of rail vehicles
- identification and definition of suitable maintenance-relevant performance criteria of rail vehicles with different drive concepts
- development of a model for the quantitative estimation and evaluation of the corresponding maintenance effort (in terms of necessary spare material and man hours) for different operating scenarios and maintenance strategies
- carrying out comparative studies regarding the maintenance of conventional rail vehicles and trains with novel propulsion concepts (e.g. hydrogen-based or battery-electric)
- investigation of the use of prognostic-based planning approaches and their impact on the subsequent operation
- scientific publication and presentation of results at project meetings and international conferences
