RMS : Maiden voyage

Both Olympic and Titanic registered Liverpool as their home port. The offices of the White Star Line as well as Cunard were in Liverpool, and up until the introduction of the Olympic, most British ocean liners for both Cunard and White Star, such as Lusitania and Mauretania, sailed out of Liverpool followed by a port of call in Queenstown, Ireland. Since the company's founding in 1871, a vast majority of their operations had taken place out of Liverpool. However, in 1907 White Star established another service out of the port of Southampton on England's south coast, which became known as White Star's "Express Service". Southampton had many advantages over Liverpool, the first being its closer proximity to London.^[90]
In addition, Southampton, being on the south coast, allowed ships to easily cross the English Channel and make a port of call on the northern coast of France, usually at Cherbourg. This allowed British ships to pick up clientele from continental Europe before recrossing the channel and picking up passengers at Queenstown. The Southampton-Cherbourg-New York run would become so popular that most British ocean liners began using the port after World War I. Out of respect for Liverpool, ships continued to be registered there until the early 1960s. Queen Elizabeth 2 was one of the first ships registered in Southampton when introduced into service by Cunard in 1969.^[90]
Titanic's maiden voyage was intended to be the first of many trans-Atlantic crossings between Southampton and New York via Cherbourg and Queenstown on westbound runs, returning via Plymouth in England while eastbound. Indeed, her entire schedule of voyages through to December 1912 still exists.^[91] When the route was established, four ships were assigned to the service. In addition to Teutonic and Majestic, the RMS Oceanic and the brand new RMS Adriatic sailed the route. When the Olympic entered service in June 1911, she replaced Teutonic, which after completing her last run on the service in late April was transferred to the Dominion Line's Canadian service. The following August, Adriatic was transferred to White Star's main Liverpool-New York service, and in November, Majestic was withdrawn from service impending the arrival of Titanic in the coming months, and was mothballed as a reserve ship.^[92]^[93]
White Star's initial plans for Olympic and Titanic on the Southampton run followed the same routine as their predecessors had done before them. Each would sail once every three weeks from Southampton and New York usually leaving at noon each Wednesday from Southampton and each Saturday from New York, thus enabling the White Star Line to offer weekly sailings in each direction. Special trains were scheduled from London and Paris to convey passengers to Southampton and Cherbourg respectively.^[93] The deep-water dock at Southampton, then known as the "White Star Dock", had been specially constructed to accommodate the new Olympic-class liners, and had opened in 1911.^[94]
