withdraw the last remaining members of the class from traffic. At the time of her withdrawal following the closure of the line, No. 32636 (formerly No. 72 Fenchurch) was the oldest working steam engine in British Railways ownership. Numbering The locomotives were originally numbered between 35 and 84, and most were given names of London boroughs or other areas of local importance which were served by the LB&SCR suburban trains they were built to operate (such as Whitechapel, Surrey and Thames), and indeed also after areas around Brighton itself, such as Kemp Town. However, there were exceptions, such as No.82 which was, in fact, named after Box Hill, a peak of the North Downs in Surrey, just outside Dorking. From 1900, the two-digit numbers were prefixed with a 6 and their names were replaced with the inscription LBSC on their side tanks (for example, No. 55 Stepney became No. 655). This was fairly standard LB&SCR practice; as engines got old, they were given higher numbers so that newer engines could have lower numbers. Further renumbering took place under Southern Railway ownership. Initially, most locomotives retained their pre-Grouping numbers with a letter prefix denoting the main works that was responsible for maintaining the class. Ex-LBSC locomotives, being maintained at Brighton, received B prefixes, thus engine No.654 became B654). The exceptions to this rule were the engines based on the Isle of Wight, which were given a "W" prefix. In 1930 this system was replaced by a new numbering scheme, whereby former LB&SCR engines had their numbers increased by 2000. Under this scheme, No. B654 became No.2654. A final renumbering in British Railways ownership saw the remaining members of the class renumbered by the addition of 30000 to their Southern Railway numbers (2678 becoming 32678, for instance), in line with the national renumbering scheme drawn up by British Railways in 1948. The famous Brighton Works shunting engine 377S (i.e. no. 377 in Service stock), by this stage the only member of the class not in revenue earning service, became DS377 (the "DS" standing for Departmental, Southern region). Preservation Ten members of the class have been preserved, chiefly in the South of England. The engines are listed in order of their LB&SCR identity; the identity in bold is their current running identity as of September 2022. Note: Numbers and Names in bold indicate what the engine presently wears. Preservation history No. 55 Stepney
