At privatisation the services became part of West Anglia Great Northern, becoming their sole route in 2004 when the West Anglia services were transferred to 'one'. In April 2006 the services became the responsibility of First Capital Connect. In September 2014, the Department for Transport transferred the new Thameslink, Southern and Great Northern franchise to Govia Thameslink Railway. When the Thameslink Programme is completed in 2018, many of these services will become part of the Thameslink network, running through central London to destinations south of the River Thames.
