This inventive color 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 different speakers’ 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 photocopiable 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.
