A cat is recovering after stowing away in an express train and travelling 1,700 miles (2,735km) in two days.

Polly, from Plymouth, climbed into a compartment after she had been injured and ended up travelling between Penzance, Plymouth, Bristol, Swansea, Worcester, Oxford and London in "freezing" conditions.

She is being treated by a vet in Penzance is due to return to her retired train-driving owner in Plymouth via a cat-box soon.
