This inventive colour picture book uses the metaphor of a train to teach basic conventions of conversation to children with autism spectrum disorders (ASDs). Engines are like greetings; they get the train going. Freight wagons are like different speakers’ turns; it’s good to have a minimum of a couple of if you end up in conversation. A set of points guiding a train from one track to every other is sort of a tactful change within the topic of conversation. When a conversation veers off-topic it is sort of a derailed train. In addition to attractive colour photographs of trains, the book comprises engaging photocopiable worksheets and colouring pages to assist promote skill generalisation. This highly visual approach to conversation is ideally suited to children with ASDs aged approximately 5-13.
