 One of the most notable features of the Cunard Building are the large basement and sub @-@ basement levels that initially acted as storage facilities for both the Company 's property and also the luggage of passengers . Coal was also stored in the basement , with a small railway track providing a link to the boiler room , which was used to heat the building . Many original features of the basement still exist , including the timber baggage racks , ship logs and other maritime documents . Several secure vaults , which in the past were used to store the most valuable passenger items , are still used today to hold historic documents , drawings and blueprints relating to the Cunard Building and also some of Cunard 's Liners , such as the RMS Queen Mary .
