There are a number of special trains which are only passing now and then, so yes. Sometimes they're just painted in a special way, but at other times they're different physically, with maybe extra facilities (I went a couple of times on some sets which had newly installed coffee machines in a designated car. The train also had a very different (and nice) look. Used for the 'limited express' service).
