The locomotive which still holds the world speed record for a steam train was back on the mainline today.

But on this occasion Mallard was being towed and wasn't in steam.

She was moved this afternoon from the National Railway Museum at York to the the NRM's base at Shildon in County Durham.

I managed to get a quick shot of both Tornado, Mallard and the class 47 loco Prince William passing just north of a place called Longlands junction.

I'm not really a train buff, but it still impresses me that a steam train ever managed to get to 126 miles an hour.

Hats off to the amazing locomotive engineer Sir Nigel Gresley who designed her.
