"the Commission have decided to depart from the electrification systems hitherto used in this country and to adopt as a standard for future electrification the use of an overhead supply of alternating current at industrial (50-cycle) frequency, generally at a pressure of 25kV. They except from this ruling only those parts of the Southern Region where a change in the existing third-rail system is not practicable.
The following chapters, after providing a brief historical review of railway electrification in Britain and elsewhere, outline the origin and nature of the technical data upon which the Commission have based their decisions."
