Register of Infrastructure
Based on national regulations of the Railway Interoperability Law (TEIV as amended and promulgated on 23. June 2008, Federal Law Gazette I S. 1092) a register of infrastructure has to be published to comply with all applicable TSI's.
The register of infrastructure of DB Netz AG is divided into a text part (Principles) and the interactive map (ISR-Viewer).
The principles contain information about the DB infrastructure manager, legal and technical background as well as more detailed descriptions of technical parameters of the infrastructure, which are generic or due to their complexity cannot be represented in the interactive map.
