About the train in the Nourish commercial: the closest paint scheme I can find that matches what is seen in the commercial is the West Coast Express, which is a commuter operation in the Vancouver, BC, area. Quite a few commercials (especially car commercials) are being filmed in Canada, especially in and around Vancouver and Toronto. Apparently it is still cheaper to film there than in the USA. Of course, the commercial "people" could have had their own train painted in their own livery.
Oh, and about the "Titanic": I liked the movie; it was a way for me to get a look into history--the design and features of the ship, the people, the fashions, the ways of life of the time. The two young lovers (though fictional) helped to bring faces to the tragedy, which before I had only read about in history books. There is only so much information you can get by reading names and events. Also, there are new discoveries as to hows the ship sank and in what order events happened that the movie was able to show that earlier efforts did not. People are certainly welcome to their tastes and opinions, but I liked the movie.
