The European Commission has set up a Rail Market Monitoring Scheme (RMMS) in order to meet the requirements for monitoring the rail market. The RMMS was implemented in 2015 with Regulation (EU) 2015/1100 on the reporting obligations of the Member States in the framework of rail market monitoring, which regulates the content and data to be submitted to the European Commission. The RMMS report is published every second year and gives an overview of the rail market.
