The construction of the station and its
branch line was part of the development of Stansted into London's third airport. In June 1985, the
UK Parliament approved the expansion of the airport. In November 1985, British Rail submitted a proposal for a
rail link to the airport, which included a new
double-track branch line connecting to the West Anglia Main Line, north of (which was
Stansted railway station at the time). The line included a
bored tunnel under the airport's runway, designed by
Sir William Halcrow & Partners, and built by John Murphy Ltd. Construction began in 1988 and the branch was completed in 1991, at a cost of £44 million. ==Layout==
