When Titus Took the Train

Titus is going on a long train journey. Under the watchful eye of the train guard he takes his seat — and until he arrives at his destination, he doesn't leave it. Or does he? Is it really bandits on the train roof, a T-rex in the tunnel, a daredevil parachute jump, and an avalanche of boulders? Or is it all part of the wild parallel universe that is Titus's imagination?
