    Abstract - (Show below) - (Hide below)

    This Technical Report (TR) is applicable to all work activity on or near the overhead contact line [IEC 60050 811, definition 811-33-02] of railway installations with supply voltage values as described in Table 1, derived from EN 50163. This Technical Report applies to requirements for safe working and maintenance procedures. It applies to all electrical work activities as well as non-electrical work activities. This Technical Report deals with the electrical hazard only. Risks coming from train traffic are not covered in this document. This Technical Report does not apply to: -guided mass transport systems such as tramways, elevated and underground metro railways, mountain railways, trolley bus and other conductor rail systems; -mine or other internal industrial material transportation railways; -railway installations with supply voltage values below 1 500 V; -experimental electrical research work.
