 "Servia" differed from earlier Atlantic liners in a number of significant ways, but most notably, she was the first liner to "specialise" in passenger transportation, due to her cargo space being sacrificed for her large power-plant.This sacrifice was viable because at that time, tramp steamers had taken over much of the freight across the Atlantic, while the demand for passenger transportation had increased.Because of her passenger specialisation, Servia is considered to be first liner of what became known as the Express Transatlantic Service.
