The Railway Children (Readings Classics)

When their father is mysteriously taken away, Roberta, Phyllis and Peter have to leave the comfort of their London house for a humble dwelling in the country. There is not much to do there, no places to go either, save the nearby railway station. The children like it. They befriend the porter and the stationmaster. They make it a habit to wave everyday to the same old gentleman on the London train. They hardly have a clue that the railway will not only fill their lives with adventure but also help unveil the truth behind the disappearance of their father.
