The London Overground is set to expand into Hertfordshire next year.

Two Herts stations will become part of the tranche of new stops on the orange line from 2015.

The stations; Cheshunt and Theobald’s Grove, in Waltham Cross, will join others in Chingford, White Hart Lane and Enfield Town among others.

TfL’s Director of London Overground, Mike Stubbs, said: “In July 2013 the Secretary of State agreed to devolve some West Anglia Main Line services to the Mayor and we are working with the Department for Transport and Abellio Greater Anglia to deliver a full transfer in 2015.

“It is our intention that these services will become part of the London Overground network, which is now one of the most reliable railways with some of the highest levels of customer satisfaction across the UK.

He added: “We are currently in the process of determining what further improvements need to be made at stations and on trains on the routes and a programme to deliver these once the railway has transferred. “However, from day one TfL and its operator will deliver passenger benefits such as staff at all stations during hours of service and full integration with TfL services including travel information and planning tools.”
