THE world's most famous steam train was in Hampshire yesterday.

For the first time ever, the Flying Scotsman ran the ten miles of the Watercress Line between Alresford and Alton and back, celebrating the relaunch of a part of the line which has been closed for over a year.

The record breaking locomotive was carrying special guests including actors Sarah Parish and James Murray and a host of civic dignitaries and business leaders.

Unveiling a plaque to commemorate the event, broadcaster and Watercress Line patron Alan Titchmarsh said: "This is such a special day for all of us. The best celebrity ever to open a bridge is the Flying Scotsman at 97 years old.

"It’s the most wonderful time warp, you come over the bridge to the Watercress Line and you are back in your childhood.

"What an honour this is for me as a lifelong steam engine fanatic to be here today."

Around 300 local schoolchildren waved Union Jack flags and detonators went off as the Flying Scotsman passed the Whitedown Lane bridge near Alton, which has been rebuilt to improve road access beneath for a new housing development.

Hundreds of railway enthusiasts lined the route as the iconic locomotive conquered the one in 60 'over the Alps' climb to the summit at Medstead and Four Marks, one of the steepest sections of line in southern England.

The Flying Scotsman will be in public service on the Watercress Line for four running days on February 29 and March 1, 7 and 8.
