The 4Cor type units survived long enough in [[British Rail]] ownership to be allocated [[TOPS]] '''Class 404'''. The '''Cor''' designation had previously been used for the [[SR Class 6Pul|6Pul units]] and was reused by them during [[World War II]] when the Pullman car was stored, but this stock was different from the 4Cor units. {{British Rail EMU}} {{transport-stub}} [[Category:Southern Railway (Great Britain) electric multiple units|4COR]] [[Category:British Rail electric multiple units|404]]
