Green Line is a long-standing commuter coach brand in the Home counties of England. The trademark is owned by Arriva,[1] with services operated by Arriva Herts & Essex.
Green Line Coaches Limited was formed on 9 July 1930 by the LGOC, which from 1927 had built up a network of coach services from London to towns up to 30 miles away, comprising 60 vehicles on eight routes. These services were largely started in response to the emergence of numerous small independent operators, often running single routes. As well as express services operated by LGOC, some were run by subsidiary companies such as East Surrey Traction & Autocar Services and some on LGOC's behalf by the National Omnibus & Transport Company. The Green Line livery and fleetname was rolled out across the existing express services,[2][3][4] differentiating these from LGOC's red service buses.
New services quickly followed, with the number of routes increasing to 27 by October 1931 and the number of coaches to 275. Green Line also began to acquire some of its independent competitors. The laying over of coaches in central London began to create congestion, so, to relieve this, some routes were linked to form cross-London services, and a short-lived coach station was opened in Poland Street, Soho at the end of 1930.[2][3]
On 1 July 1933, Green Line passed to the new London Passenger Transport Board and competing services within the London Passenger Transport Area were absorbed into the network. Various vehicles of numerous different types were inherited, and much effort was made in replacing these with a standardised fleet of vehicles from late 1936. Poland Street coach station was closed, and almost all routes were linked to run across London.[2][5]
Services were suspended during World War II, resuming in February 1946.[6] Routes in 1949:
701 Gravesend to Ascot
702 Gravesend to Sunningdale
703 Wrotham to Amersham
704 Tunbridge Wells to Windsor
705 Sevenoaks to Windsor
706 Westerham to Aylesbury
707 Oxted to Aylesbury
708 East Grinstead to Hemel Hempstead
709 Godstone to Chesham
710 Crawley to Amersham
711 Reigate to High Wycome
712 Dorking to Luton
713 Dorking to Dunstable

715 Guildford to Hertford
716 Chertsey to Hitchin
717 Woking to Welwyn Garden City
718 Windsor to Epping

722 Upminster to Aldgate
723 Tilbury to Aldgate
726 Baker Street to Whipsnade (summer only)

More services were added, and the routes were given numbers in the 700 series. Ridership increased to a peak of 36 million passenger journeys a year between 1957 and 1960. In 1962, AEC Routemaster double-deck coaches were introduced on some routes, notably route 721 which ran every 12 minutes at peak times, and route 704 conveying tourists to Windsor and Royal Tunbridge Wells.[7][8][9][10] Orbital coach routes commenced:
In 1970, London Transport became the responsibility of the Greater London Council, so control of Green Line was passed from London Transport to London Country Bus Services, part of the state-owned National Bus Company. Patronage was declining, partly as a result of increasing car use and quicker parallel rail services, and the last cross-London routes ceased in 1979.[2]
By this time, the orbital services 724 and 726 (a variant of the 725) had been revised to serve Heathrow.[11] Green Line also became a National Express operator.
In 1986, London Country was divided into four operating companies to prepare for privatisation.[12] They were sold separately, and ownership of the Green Line network became fragmented, with only a few routes surviving. The airport services passed to Jetlink and are now operated by National Express.
Following closure of its Bracknell depot in 2015, First Berkshire services were revised and routes 700 and 701 were discontinued. Reading Buses took over operation of route 702 on 24 December 2017.[14] On 8 May 2018, the 702 was withdrawn between Legoland Windsor and Bracknell. On the same day, route 703 was introduced under the Green Line brand, running between Heathrow Terminal 5 and Bracknell, replacing the withdrawn section.[15][16]
In June 2023, it was announced that these services would no longer use the Green Line brand, replacing it with "London Line" for service 702 and "Flight Line" for service 703.[17]
On 4 December 2021, route 758, operated by Arriva Herts & Essex, was withdrawn, citing long-term low passenger numbers made worse by the COVID-19 pandemic.[19]
On 2 November 2025, the 755 route number was withdrawn. Journeys from Leagrave, Marsh Farm and Warden Hill now operate as part of route 757.[20]
Routes 724 and 725 no longer use the Green Line brand.[21][22] Route 757, operated by Arriva, is the only service now using the Green Line brand, promoted on their website as Greenline 757.[23][24]
