This toy is designed with an optical sensor inside so it can read any black line and follow the direction automatically. If you put the train anywhere, it will keep going in circles until it locates the line. Once it finds the line, it will keep following it. This is battery operated and can provide a maximum of 25 minutes of working time. It is made of high quality ABS, which is BPA free and super durable
