Rail capacity at London Gatwick will "double" in the next five years with a train departing the airport every three minutes, it was claimed today.
New rolling stock will be added to several railway lines to Gatwick in the next three years.
In early 2016, new Gatwick Express trains, with 108 new Bombardier carriages "designed specifically for the airport passenger", will enter service between LGW and London Victoria.
How it will look in 2020: London Gatwick's train station concourse
The first new Thameslink trains serving Gatwick are due to be added to the Brighton to Bedford line next spring, according to manufacturer Siemens. From 2018, these trains will also run on two new direct services between Gatwick and Peterborough and Cambridge.
Gatwick today said these upgrades will result in a doubling of train services to/from the airport.
It said every hour there will be four Gatwick Express trains to Victoria; six other trains to Victoria; four trains to Beford via London Bridge; two trains to Cambridge via London Bridge; two trains to Peterborough via London Bridge; and two trains to London Bridge.
Gatwick's train station will also undergo a £120.5 million refurbishment by 2020, more than doubling the size of the concourse area (see news, December 4).
Guy Stephenson, Gatwick's CCO, said: "The new high frequency service that will serve Gatwick will transform rail journeys for our passengers, with capacity doubling and a train to London every three minutes.
"Crucially, the new trains will be much more reliable and will be stacked with amenities suited to the needs of air travellers. Combined with robust new track and signalling systems, Gatwick's passengers will experience a really pleasant and dependable service.
"Overall, the improvements to Gatwick's rail service means that 15 million people will be brought within 60 minutes of Gatwick by rail – the best reach of any UK airport."
Gatwick is currently campaigning for a second runway. It recently emerged that the Liberal Democrats are opposed to runway expansion at any airport in the UK, according to their election manifesto (see news, April 20).
