Hi, I just read your post, the reason White Star put four funnels on the Olympic class ships Titanic,Britanic,Olympic is four funnels helps convey the sheer size and power of these ships. The thinking of the day was the more the better, as weird as it sounds. White Star was in a fierce battle with other shipping companys over the Trans Atlantic route so even though the fourth funnel was a dummy it helped with the look. One of the fireplaces in 1st class smoking room i think was piped up through the funnel so alittle smoke could be seen coming out. I hoped I answered your question. I have hundreds of items books,papers models, all sorts of Titanic material. I have been a Titanic buff for over thirty five years. Any other questions? You can write me at or ok.
