VRIOGS 010.7 Revision A 5SECTION 4.0FURTHER DEFINITIONS4.1 Electrified TracksElectrified tracks are defined as tracks where electric traction units are expected torun and where provision for traction current supply is maintained.The rails of electrified tracks shall be equipped to carry the traction return current forthe electric traction units. This shall include provision for the designed normalservice and peak traction return current on a continuous basis and also for themaximum potential fault currents.4.2 Electrified AreaThe electrified area is defined as the entire rail corridor under and between anyelectrified tracks and extending on each side to the nearer of either the rail corridorboundary or a line 15 m from the centreline of the electrified track nearest to theboundary, so long as that line is outside the envelope of all traction supply equipmentstructures for the electrified tracks.The extents of the electrified area are illustrated in Figure 1 and Figure 2.Figure 1 Transverse boundary of Electrified AreaAny non-electrified track that lies within the electrified area shall be considered aspotentially subject to a direct traction fault.The distance from an electrified track that may be considered as susceptible to directtraction faults may vary under different systems of electrification and differentAccredited Rail Organisations regimes.NOTE: This document is controlled only when viewed on the DOT Engineering Standards website.Any other copy of this document is uncontrolled, and the content may not be current.
