The
Construction
The SL (South London stock) units were built in 1909 for use on the
The Trailer First cars were later removed and used as locomotive-hauled stock, from when the driving cars were paired with former loco-hauled coaches converted to Driving Trailer Composite cars.
After the replacement of the AC overhead equipment by the standard SR 660 V DC third-rail system on 17 June 1928,[1] these units were rebuilt. The Driving Motor cars were paired together again to form eight units designated 2SL. The Trailer First cars (which had been out of EMU stock for nearly twenty years) were included in this programme, and were rebuilt into Driving Motor and Driving Trailer pairs to form four units designated 2Wim, for use on the Wimbledon-West Croydon line.
Formations
The LB&SCR purchased sufficient cars for 8 permanent sets, numbered 1E to 8E. However, later Brighton practice was to dispense with fixed sets.

When the units were reformed into 2-car sets, 14 driving trailers were provided for 16 driving motor cars, because it was found that the motor cars required more time under maintenance. [2]
