This inventive picture book uses the metaphor of a train to teach basic conventions of conversation to children with autism spectrum disorders (ASDs). Locomotives are like greetings; they get the train going. Train cars are like conversation turns; it is good to have at least a few when you are in conversation. A switch track is like a tactful change in the topic of conversation. When a conversation veers off-topic it is like a derailed train. As well as attractive color photographs of trains, the book contains engaging fill-in-the-blank worksheets and coloring pages to help promote skill generalization. This highly visual approach to conversation is ideally suited to children with ASDs aged approximately 5-13.
