== Purpose/necessity of this article == 

 I can see that someone has put a lot of hard work into this article, but I really don't see why it is necessary.  CityLink is merely a brand that Central Trains use for its long-distance services, that's all.  It's not a separate company, or a separate franchise: it is only a brand.  As far as I can see, it merely duplicates material from the Central Trains article.  What do others think?
