'one' is the train operator providing services to London Liverpool Street and the East of England.

ONE Railway operates local, suburban and express services from London Liverpool Street in the City of London to East and North London, Essex, Hertfordshire, Cambridgeshire and East Anglia, otherwise known as the Greater Anglia network.

‘one’ is part of the National Express Group and brings together the train services previously provided by Anglia Railways, First Great Eastern, the West Anglia part of the WAGN operation and Stansted Express.
