Established in the 1860s, the rail link between Cork and Queenstown augmented the increasing use of the harbour as a transatlantic port. Baggage and Mail was transported here by train and loaded onto tenders at the Deepwater Quay which was developed in 1882.

First and Second Class passengers for the Titanic boarded the tender "Ireland" here. The tender "America" departed from White Star Line Pier with the Third Class Passengers to pick up mail and baggage from this Quay before leaving to board the great liner anchored at the mouth of the harbour.
