A missing cat has been rescued from an inter-city train - after stowing away in the undercarriage for a staggering 1,700 MILES. Polly the tabby, who had a badly-broken leg, is thought to have climbed on board the high speed express near her home in Plymouth, Devon. She then spent a terrifying TWO days trapped under the front carriage as the train thundered between the West Country, London and South Wales. The lucky two-year-old was only discovered when train manager Emily Mahoney-Smith heard her miaowing for help when the train stopped briefly on its way to Cornwall.
