Sheppey Light Railway, Westerham, Hundred of Hoo (passengers only), and Gravesend West. By the 1980s, the Channel Tunnel was being built and a new high-speed link was needed to access St Pancras, but the choice of route was contentious. Before it opened, Eurostar trains had conductor shoes fitted and ran on primarily the South Eastern Main Line and other third rail lines to London Waterloo. Phase 1 of High Speed 1 opened in 2003 to near Gravesend and the line fully opened in 2007. There are two stations on the rail link in Kent, Ebbsfleet International between Dartford and Gravesend and Ashford International both offering services to Lille, Paris and Brussels. Extra commuter services to London served by Class 395 "Javelins" were introduced in 2009. The late 1980s saw the organization of the railways change again, first with the "sectorisation" of British Rail with the abolition of the "Southern Region" and introduction of Network SouthEast for passenger services. The railways were privatised in 1996, with most Kent passenger services being run by Connex South Eastern (14 October 1996 to 9 November 2003). Connex encountered financial difficulties but embarked upon the mass replacement of the large obsolete rolling stock fleet. A temporary government owned Train operating company, South Eastern Trains ran from November 2003 to March 2006 to be replaced by the current incumbent Southeastern. Southern also run some services to and . In addition to the "mainline" railways there are several light, heritage and industrial railways in Kent. There are three heritage, standard gauge railways; Spa Valley Railway near Tunbridge Wells on the old Tunbridge Wells West branch, East Kent Railway on the old East Kent coalfield area and the Kent and East Sussex Railway on the Weald around Tenterden. In addition there is the 15 inch gauge, tourist oriented Romney, Hythe and Dymchurch Railway on the south east Kent coast along the Dungeness peninsular and the 2 ft 6in, ex industrial Sittingbourne & Kemsley Light Railway. Air Kent was the forefront of the development of aviation in the UK with the Royal Aero Club in 1901 at Leysdown on the Isle of Sheppey for balloon flying. This soon explained with the Short Brothers starting to base Wright flyer from Shellbeach in July 1909. This soon moved to nearby Eastchurch. Shorts moved production to Rochester in 1913, where they constructed seaplanes along the banks of the River Medway and aeroplanes
