Due to the fact that the vault bridges in DB Netz AG's inventory are getting older and older, a consistent approach to these historic structures must be taken. Based on the systematically recorded and classified damages, a deck slab or a sealing with beam construction between the upper edge of the vault and the upper edge of the rails should be implemented. A complex fundamental renewal should be carried out on the structure, e.g. drying of the structure, sealing with a new drainage system and the creation of the required safety space. In order to effectively implement this concept, a comprehensive module is to be introduced in the regulations of the Deutsche Bahn.
