The [[Southern Railway (UK)|Southern Railway]] created '''classification and numbering systems''' for its large fleet of [[electric multiple unit]]s, perpetuated by the Southern Region of [[British Rail]] until the early 1980s, when the impact of [[TOPS]] was felt. Some stock is still allocated Southern-style classifications in a semi-official manner.
