Spook trains in the dead of night! And they seem to vanish into thin air - but where do they go? The Famous Five are on to it! But discovery of an unusual underground tunnel system, and a secret train-service, has them puzzled. If they follow the tracks, will they solve the mystery? These classic editions feature Enid Blyton's unchanged text and Eileen A. Soper's original illustrations.
