Olympic and Titanic-1-

Olympic and Titanic, both Royal Mail Ships.

Royal Mail ships were transatlantic liners who carried post over the Atlantic Ocean. Olympic, Titanic, Lusitania and Carpathia were all Royal Mail Ships. An abbreviation for the Royal Mail Ships is RMS, which was (and still is) used by ships at the beginning of their names.

Postal workers on board the ships were hired separately from the rest of the ship's crew, and were responsible for sorting mail en route to America, and then on the journey back to the United Kingdom.
