  London Overground Rail Operations Limited was a train operating company contracted to operate the London Overground train service on the National Rail network, under the franchise control of Transport for London. The company was a 50/50 joint venture between Arriva UK Trains and MTR Corporation.
  
  ## History
  
  On 20 February 2006, the Department for Transport announced that Transport for London would take over management of services then provided by Silverlink Metro.
  
  In June 2006, Transport for London announced that Govia, MTR/Laing Rail, National Express and NedRail had been shortlisted to bid for the London Rail Concession. In September 2006, Transport for London announced that the extended East London Line would be included, and the operation branded London Overground.
  
  In June 2007, Transport for London awarded the concession to MTR Laing, and operations started on 11 November 2007. The concession was for six years, four months until 31 March 2014 with a two-year extension option. The option was taken up with the concession to end on 12 November 2016.
  
  In December 2007, Henderson Group, the parent company of John Laing plc, announced the sale of the Laing Rail division, which comprised half of LOROL, Chiltern Railways and a stake in the Wrexham & Shropshire open-access railway operator. In April 2008, Laing Rail was bought by the German Government's rail operator Deutsche Bahn, which now holds a 50% stake in LOROL. The price was said to be around €170 million. Laing Rail became part of DB Regio, before a restructuring saw it moved under the control of Arriva UK Trains.
  
  In April 2015, Transport for London placed a notice in the Official Journal of the European Union, inviting expressions of interest in operating the next concession. On 31 May 2015, London Overground Rail Operations took over the Liverpool Street to Enfield Town, Cheshunt (via Seven Sisters) and Chingford services, as well as the Romford to Upminster service, from Abellio Greater Anglia.
  
  In July 2015, Transport for London announced the shortlisted bidders for the next concession were Arriva UK Trains, ComfortDelGro, a Keolis/Go-Ahead joint venture and MTR Corporation. In March 2016, Arriva Rail London was awarded the concession commencing 13 November 2016.
