STEAM locomotive Tornado is celebrating a milestone with 100,000 miles in service since being completed in 2008.

The A1 Steam Locomotive Trust, the charity behind the famous 100mph new locomotive, said it went through the 100,000 mile barrier just outside Pickering on the North York Moors Railway on Sunday, while hauling the last train of the day to Grosmont.

Tornado has served on the Network Rail mainline and heritage railways across the country. Highlights have included three Royal Trains, including being officially named by the Prince of Wales and Duchess of Cornwall in February 2009, and the BBC Top Gear Race to the North with Jeremy Clarkson on the footplate.

It also rescued stranded commuters in Kent and hauled the Winton train to commemorate the 70th anniversary of the Kinder Transport.

The engine remains the only new mainline steam locomotive to be finished in Britain since 1960.
