What is SR multiple unit numbering and classification?
The [[Southern Railway (UK)|Southern Railway]] created classification and numbering systems for its large fleet of [[electric multiple unit]]s that were perpetuated by the Southern Region of [[British Rail]] until the early 1980s, when the impact of [[TOPS]] was felt. Even now, some stock have still been allocated Southern-style classifications in a semi-official manner. ==Related pages== {{British railway rolling stock numbering and classification}} {{transport-stub}} [[Category:Multiple units]]
