8 This includes: overhead line equipment and its structures and foundations the trackside switching stations transformers bonding isolationAn isolation that has been carried out by the ECO when it isessential to switch off the electrical supply immediately, to removedanger to personnel from live OLE. An emergency isolation is carried out by the ECO switching off theelectrical supply to all lines: between neutral sections (these are typically 15 miles apart), or between a neutral section and the end of an electrified line. In certain locations, equipment is provided to shorten the area ofthe emergency form of construction where the overhead line equipment issupported by wires crossing the lines below suspended frommasts on each side of the track.
