You don't have to like trains to love this simple and witty book. Trundling down the track goes a typical freight train, made beautiful by its bright colours, from the red guard's van through to the black tender and steam engine. Bold and clear, the colours stand out, until the train gathers speed and they are all whirled together as it hurtles through tunnels, over bridges, through night and day until, as trains do, it disappears. Nothing is said, nothing needs to be said; it's just a very satisfying experience. And a good introduction to colours, too.
