Electrified railways are usually supplied from feeder stations (AC traction) or sub-stations (DC traction) located at intervals along the line. Section Isolators are placed in trackside rooms at the boundaries between the feeds from two adjacent feeder stations. They are often referred to as Track Section Cabins. In addition to the track sectioning cabins, catenary isolators will be provided at strategic locations (crossovers and junctions) to facilitate maintenance and to minimise the operational impact of any catenary incident. These isolators will be either manually operated or motorised depending upon their respective safety and operational importance.
