Britain's biggest construction project and first high-speed rail link are officially opened by the Queen

The opening of St Pancras by the Queen today marked not only the completion of Britain鈥檚 biggest construction project but also the arrival of a 68-mile high-speed rail link from Central London to the Channel tunnel.

The rail link, which is called High Speed One and took 13 years and 拢5.8bn to build, has finally enabled the English to catch up with the French, reigniting our enthusiasm for train travel.

Eurostar trains will arrive in Paris from St Pancras just two hours and 15 minutes later, having travelled at 186mph and shaving 20 minutes off the journey time.

The 拢800m refurbishment of the station involved restoring the 1868 trainshed designed by Thomas Barlow and its neo-gothic, grade-I listed brick shell by George Gilbert Scott.

Contained within what was once the widest single-spanned structure in the world, there are now six Eurostar platforms, international departures and arrivals lounges, passport controls and of course Europe's longest Champagne bar.
