Research questions: 1. What bottlenecks can the railway domain encounter when developing safety-critical software? 2. How can Industry 4.0 technologies be applied to overcome thebottlenecks and improve the development process of safety-critical software? Methodology: The study is based on a qualitative research methodology following an abductive approach. This led to the theoretical framework being gradually developed in parallel with the empirical data collection. The theoretical collection was based on scientific reports and books. The empirical data collection was based on a questionnaire, of which five in-depth interviews werethen conducted based on responses. Out of the five, three were semi-structured and two unstructured. Conclusion: The study concluded that all phases except design and implementation and software evaluation contained various bottlenecks related to tools, training, processes, resources and communication. However, it can be concluded that the testing phases were the biggest bottleneck at Alstom. To overcome testing challenges and improve the development process, the analysis shows that Industry 4.0 technologies such as AI, NLP and ML could be used to automate testing activities.
