Naughty Frankie! The adventurous Jack Russell from Gravesend, Kent, recently gave his owners the slip during the early hours and ran away to London. (What a wag! He must be barking mad! Etc, etc...)

But rather than travel on foot, Frankie's incredible journey involved an eventful 50-mile train ride from his local station to King's Cross.

Having waited patiently alongside commuters on the platform, the ticket-dodging pooch boarded the 6.56am service, where he enjoyed 30 minutes of freedom (and possibly read a couple of free newspapers while drinking a lukewarm coffee) before train manager Richard Cheeseman apprehended him.

Quick-thinking railway staff called the phone number on the dog's collar. And Frankie's frantic owners, Jane Abbott and her daughter Stephanie, jumped on a later service to retrieve him.

"What we don't understand is why Frankie chose rail as he's never been on a train before," Jane told The Sun. Hmmm... maybe he'd just missed the coach.

Anyway, all's well that ends well - because the four-legged explorer is now back home with his family...

(In case you were wondering, that's Jane's son, James, on the end.)

And if you fancy seeing exactly what Frankie got up to during his big day out, take a look at these tell-tale pictures taken from CCTV...
