Stansted Airport railway station is on a branch line off the West Anglia Main Line in the east of England and was opened in 1991 to provide a rail link to London Stansted Airport. It is 36 miles 67 chains (59.3 km) down the line from London Liverpool Street station, to which a frequent dedicated service called the Stansted Express operates. The short branch line was constructed at a cost of £44 million and opened by British Rail to coincide with the completion of the airport's new terminal building.
