Units selected for withdrawal were usually those with high mileage or in poor condition. By mid-2005 only a handful of units remained in traffic. The final diagrammed passenger service out of London was the 17:17 London Victoria to Eastbourne and Seaford on 19 August 2005, formed of units 3486 and 3535, plus 4 CIG unit 1866. Six units were subsequently retained for emergency cover. Unit 3514 was used on the Sussex Slammer railtour on Saturday 19 November 2005. The following Saturday saw the final slam door trains on Southern, when units 3490, 3505 and 3535 formed the 09:19 Brighton to London Victoria and 11:06 London Victoria to Brighton services (via Lewes due to engineering works); this being the last scheduled mainline passenger service using southern-electric slam-door stock (the very last passenger being an off-duty HM Inspector of Railways). Following this trip the stock was withdrawn from service and initially put into Lover's Walk depot before being moved (under its own power) to Battersea Stewart's Lane Depot (road 12) from where it was hauled away at 12:26hrs on 3 January 2006 by a class 47 locomotive for scrapping. One complete 4 VIP unit has been preserved, and two 4 VOP units remained in departmental use until March 2013. South West Trains South West Trains (SWT) inherited the second-largest number of units, with an initial fleet size of 62 units. The entire fleet was composed of standard Class 423/1 units. Later, a further four units (nos. 3809-3812) were transferred from Connex South Eastern. These were also standard units, but were numbered in the 38xx series to denote they were leased from Porterbrook rather than HSBC Rail. SWT quickly repainted its fleet of units into a new livery, based on the previous Network SouthEast (NSE) livery, but with the addition of an orange stripe and the absence of the grey band. All but four units (3415 and 3809-3811) were repainted. These four units were deliberately retained in NSE livery, meaning that in the final days of slam-door trains they attained "celebrity" status among rail enthusiasts. In 2001 SWT placed an order for 785 new carriages with Siemens to allow it to replace its fleet of slam-door trains, in accordance with its franchise commitment to do so by 2005. To assist Siemens in the design of third rail units, 4 VEP no. 3810 was transferred to a test site in Germany to undergo tests.
