The [[Southern Railway (UK)|Southern Railway (SR)]] gave the designation '''CW''' to the fleet of AC [[electric multiple unit]]s used on the lines to [[Coulsdon]] and [[Wallington, London|Wallington]]. They were planned by the [[London, Brighton and South Coast Railway]], but were delayed by [[World War I]] and the [[Railways Act 1921|grouping]] and were introduced by the Southern Railway.<br />
<br />
== Construction ==<br />
The '''CW''' ('''C'''oulsdon and '''W'''allington stock) units were built in 1923–1924, as the last electric train stock for use on the [[London, Brighton and South Coast Railway|LBSCR]] AC overhead electrified lines in South London. This stock comprised some hundred carriages, which were used in five-car formations: Driving Trailer [[Travel class#Trains|Third]] (DTT) + Driving Trailer [[Travel class#Trains|Composite]] (DTC) + Motor Luggage Van (MLV) + Trailer Composite (TC) + Driving Trailer Third (DTT).<br />
<br />
The stock, built by the [[Metropolitan Carriage, Wagon and Finance Company]] at [[Birmingham]], was as follows:<br />
<br />
* 21 Motor Luggage Vans<br />
* 60 Driving Trailers<br />
* 20 Trailers<br />
<br />
The Motor Luggage Vans (nicknamed "Milk Vans") each had four {{convert|250|hp}} [[General Electric Company plc|GEC]] traction motors.<br />
<br />
After the replacement of the AC overhead equipment by the 660 V DC third rail system adopted as standard by the SR, the carriages that formed these units were rebuilt accordingly, the Motor Luggage Vans becoming bogie goods train [[brake van]]s.<br />
