The London Overground network was introduced in late 2007 to take over the former Silverlink Metro services operating from Barking, Gospel Oak, Stratford, Richmond, Watford Junction & London Euston.
A further expansion to place to the network in 2015 when former Abellio Greater Anglia services in East London, joined the London Overground Network. New destinations on the network are Enfield Town, Chingford, Cheshunt, London Liverpool Street, Romford & Upminster.
Large sums of investment have taken place across the network and is now one of the most reliable network in the country.
Transport for London Oystercards and Travelcards are valid on the London Overground network with special fares to Watford Junction.
