====High Speed 1====
{{Main|HS1}}
The first implementation of high-speed rail up to 186&nbsp;mph in regular passenger service in Great Britain was the Channel Tunnel Rail Link (now known as [[High Speed 1]]), when its first phase opened in 2003 linking the British end of the [[Channel Tunnel]] at [[Folkestone]] with Fawkham Junction in Kent. This is used by international only passenger trains for the [[Eurostar]] service, using [[British Rail Class 373|Class 373]] and [[British Rail Class 374|Class 374]] trains. The line was later extended all the way into [[St Pancras railway station|London St Pancras]] in 2007.

After the building of the first of a new [[British Rail Class 395|Class 395]] train fleet for use partly on High Speed 1 and parts of the rest of the UK rail network, the first domestic high-speed running over 125&nbsp;mph (to about 140&nbsp;mph) began in December 2009, including a special Olympic Javelin shuttle for the [[2012 Summer Olympics]]. These services are operated by the [[South Eastern franchise]].
