The [[Southern Railway (UK)|Southern Railway (SR)]] gave the designation '''2-SL''' to the small fleet of [[electric multiple unit]]s dedicated for use on the South London lines. None of these units survived long enough in [[British Rail]] ownership to be allocated a [[TOPS]] class. In Southern Railway/Region days, they mainly spent their lives as 2-car units on the ex-LBSCR Wimbledon-West Croydon Line (now Croydon Tramway) with head code 2. They were distinctive, because they retained their flat roofs over the driving cabs, where the pantographs were originally situated.

==Construction==
The '''2-SL''' ('''2'''-car '''S'''outh '''L'''ondon stock, numbers 1801–1808) units were rebuilt in 1929 from the Driving Motor cars originally used in ex-[[London, Brighton and South Coast Railway|LBSCR]] AC electric '''[[SR Class SL|SL]]''' stock. They were intended for use on the South London lines. Originally, these units had some First Class accommodation in the Driving Trailer car, but this was later declassified to Third Class only. The units were numbered 1901–1908 before 1936, when those numbers were reused for new '''[[British Rail Class 401|2-BIL]]''' units. At the same time, '''[[British Rail Class 405|4-SUB]]''' unit number 1801 was renumbered 1600.

==Formations==
Initial formations of these units were as follows:
{| class="wikitable"
!Unit Numbers
! {{abbr|DMBT|Driving Motor Brake Third}}
! {{abbr|DTC|Driving Trailer Composite}}
|-
|1901–1908 / 1801–1808
|8723–8730
|9751–9758
|}

==Withdrawal==
The majority of these units were withdrawn in 1954, the exceptions being 1802 (in 1951) and 1807 (destroyed in 1940 during a [[World War II]] air raid). All were subsequently scrapped.
