UK suburban rail network London Overground has completed ten years of service in the city after it took over from Silverlink Metro a decade ago.

The service was launched in November 2007 and serves as an orbital route around inner London, connecting 23 boroughs of the capital city and parts of southern Hertfordshire.

Transport for London (TfL) is set to publish the ‘Out and about on the London Overground’ guide to commemorate the ten-year milestone, which will include details of the majority of the city’s sights and attractions that are reachable via the London Overground.

TfL London Rail and Sponsored Services director Jonathan Fox said: “Since forming London Overground in 2007, we have focused on improving the frequency and reliability of services for customers.

“We have now seen over a billion journeys on the network and record levels of customer satisfaction, making it one of the most popular railways in the country.”

The network is also expected to see further improvement initiatives in the coming years.

Fox added: “Further improvements will include an extension to Barking Riverside and a new fleet of trains, providing improved capacity and reliability.”

The frequency of train operations increased over the last decade from 400 per day to 1,500 in this year, and the London Overground is estimated to have served around 189 million customers in 2016-2017.

The network has also incorporated three additional lines in the form of the East London line in 2010, South London line in 2012 and West Anglia lines in 2015.

Additionally, the service was noted to have scored a customer satisfaction rate of 85% in the first quarter of 2017/2018.

Oyster and contactless payments were also introduced during this period and a fifth car was added to many trains in order to increase capacity.
