ICONIC steam engine Sir Nigel Gresley is back in action, hauling passengers across one of the most picturesque landscapes in Britain.

Following minor repairs, the A4 Pacific No 60007 is steaming along the North Yorkshire Moors Railway throughout the summer.

This year marks the 50th anniversary of the locomotive setting a post-war speed record when it reached 112mph on the East Coast Main Line.

The engine was built in 1937 at Doncaster and was named after its chief architect and engineer because it was the 100th Gresley engine to be manufactured.

Many were scrapped in the Sixties as the railway moved towards diesel traction, and the Sir Nigel Gresley was withdrawn from mainline service in 1966.

Owned by the Sir Nigel Gresley Locomotive Preservation Trust, it is operated by the A4 Locomotive Society from its base on the North Yorkshire Moors Railway.

It is one of only six remaining A4 Pacific class engines in the world, two of which are based in North America.
