Great Western Railway has named a train in honour of mystery writer Dame Agatha Christie.

The best-selling author was born in Devon and lived in Wallingford for 42 years from 1934 to 1976.

The GWR Intercity Express train 802110 was officially named today at Paignton Railway Station by her grandson Matthew Pritchard.

The ceremony also celebrated the 70th anniversary of her famous play The Mousetrap and members of the cast of a touring production, which is on in Torquay, were also at the ceremony.

Last weekend around a thousand people gathered for the grand unveiling of the UK’s first life-size statue of Agatha Christie in Wallingford.

The bronze tribute, which is seated on a bench in the Kinecroft, was unveiled by Mr Pritchard.

Christie wrote 66 detective novels, including Miss Marple and Hercule Poirot, and 14 short story collections.

Dan Panes, of GWR, told BBC Spotlight the ceremony was part of the company's "100 Great Westerners, external" series of naming trains.

He said: "It's really special, and this is about us doffing our hats to those people who helped make the West [of England] great.

He added: "Today is about Agatha Christie, and it's a fantastic way to honour people."

The train company tweeted: "The secret’s been revealed! Dame Agatha Christie is our latest Great Westerner to have a named Intercity Express Train. Have any sleuths spotted it yet?"
