I've read the original version of the novel and fell in love with the story for its simple plot but excellent moral values. Hence I've decided to teach this novel in my school. The abridged version is unavailable in Johor but if you have friends from Perak, you can always ask for their help to buy you a copy.
The original 'The Railway Children' as a comparison or easy reading can be downloaded here:
