The Southern Railway (SR) gave the designation 2Wim to the small fleet of electric multiple units dedicated for use on the Wimbledon to Croydon line.

The 2Wim (2-car Wimbledon stock, numbers 1809-1812) units were rebuilt in 1930 from former Trailer First cars originally used in ex-LBSCR AC electric SL stock. They were intended for use on the line between Wimbledon and Croydon. Originally these units had some First Class accommodation in the Driving Motor car, but this was later declassified to Third Class only. The units were numbered 1909-1912 before 1936, when those numbers were reused for new 2Bil units. The LB&SCRs coat of arms, displayed above the entrance to Gipsy Hill railway station. ...

Formations
Initial formations of these units were as follows:
Unit Numbers
DMBC
DTT
1909-1912 / 1809-1812
9818-9821
9951-9954
Withdrawal
All four units were withdrawn in 1954 and subsequently scrapped.
Class390 no. 390029 "City of Stoke-on-Trent" at Birmingham New Street on 24th September 2003 with a service to Wolverhampton.
The Class390 is the fastest domestic electric multiple unit operating in Britain, (only the Anglo/French Class373 used by Eurostar is faster), with a top speed of 225km/h (140mph), although limitations of the signalling systems limit the units to a maximum speed to 125mph.
This allowed the final Class 90 locomotives to be withdrawn, and inroads were made into the main Class 87 fleet.
