Railway applications - Current collection systems - Technical criteria for the interaction between pantograph and overhead line (to achieve free access)
Combination of different overhead contact lines and pantographs will provide various interaction performances. This International Standard defines parameters for interoperability in the field of interaction between the pantograph and the overhead contact line. The standard specifies the interface requirements of rolling stock and infrastructure to achieve free access. This standard describes parameters and values for all planned lines and future lines. Annex B gives some essential parameters for existing lines. The energy supply system is not covered by this standard.
