I choose the novel The Railway Children written by Edith Nesbit. The most interesting part of the story is the saving of the train. There are many reasons why the event is the most interesting.
One day, Bobbie, Peter and Phyllis see a landslide. Part of the hill falls on the railway line. The children have to warn the next train or else there will be a terrible accident. They make flags from the girls' petticoat. When the train comes, Bobbie runs forward waving the flags. The train stops just in time.
First of all, this event is the most interesting part of the story because it shows that the children are clever. To save the next train, they come out with a very creative idea. They tie the girls' red petticoat to sticks to make flags, which they use to warn the train of danger ahead.
Apart from that, from this event we can see that the children, especially Bobbie, are brave. They know that they have to stop the train before a bad accident happen. When the train is coming very fast, Bobbie runs onto the track, waving the flags. It is a courageous act, which I think not many people would dare to do.
In a nutshell, the saving of the train is the most interesting part of the story because it shows that the children, Bobbie, Peter and Phyllis, are clever and brave. I like this story very much.
