Vehicle Maintenance


    For each vehicle, before it is used in the network, an entity responsible for its maintenance is determined and registered in the vehicle registry.

    Without affecting the obligation of railway enterprises and infrastructure managers for the safe operation of trains, the entity responsible for maintenance ensures the safe operational condition of the vehicles for which it is responsible.       For this purpose, the entity responsible for maintenance establishes a system for maintaining these vehicles, through which the system:

  • ensures that vehicles are maintained in accordance with the maintenance documents for each vehicle and the applicable regulations, including maintenance rules and the relevant TSI provisions;
  • applies the necessary methods for risk determination and assessment established in the Common Safety Methods (CSM);
  • ensures that its contractors take risk control measures through the application of monitoring methods laid out in the CSM regarding monitoring, and that this is stipulated in the contractual clauses, which are disclosed upon request by the European Union Agency for Railways or the national safety authority;
  • ensures traceability of maintenance activities.

    The maintenance system consists of the following functions:

  • a management function for supervision and coordination of maintenance functions and for ensuring the safe operational condition of the vehicle in the railway system;
  • a maintenance development function, responsible for managing the maintenance documentation, including configuration management, based on design and operational data, as well as quality and experience gained;
  • a rolling stock maintenance management function for managing the decommissioning of the vehicle for maintenance and its re-commissioning after maintenance;
  • a maintenance execution function for carrying out the necessary technical maintenance of the vehicle or parts thereof, including the documentation for commissioning.
