The railway lines of Kent, many of which Connex South Eastern ran services on

On 8 November 2003, its services were stopped because of money problems and because they were using old trains.[2]



Connex South Eastern ran train services from London Blackfriars, London Bridge, London Cannon Street, London Charing Cross and London Victoria to Hayes, Bromley North, Ramsgate, Dover Priory, Folkestone Harbour and Ore.

It also ran train services between Sittingbourne and Sheerness; Paddock Wood, Maidstone West and Strood; and Maidstone West, Redhill and Three Bridges.



Connex South Eastern took on a large fleet of slam-door and power-door electric multiple units from Network SouthEast.

The slam-door EMUs were Class 411s, Class 421s and Class 423s, built between 1956 and 1974,

the power-door EMUs were Class 365s, Class 465s and Class 466s, built between 1991 and 1995.

In 1998 Connex South Eastern leased twelve Class 508s from Angel Trains to replace some of the old Class 411s.[3][4][5][6][7]

Connex South Eastern ordered 112 Class 375s, and 36 Class 376s with the first entering service in April 2001.[8][9][10]

From 4 February to 20 March 2002, a preserved Class 201 Hastings unit was on loan to Connex South Eastern to run two return journeys on Monday to Fridays between Charing Cross and Hastings.[11] this was because there was a shortage of trains.
