Auxiliary generating sets.—In addition to the four main generating sets, there were two 30-kilowatt engines and dynamos situated on a platform in the turbine engine room casing on saloon deck level, 20 feet above the water line. They were the same general type as the main sets.
These auxiliary emergency sets were connected to the boilers by means of a separate steam pipe running along the working passage above E deck, with branches from three boiler rooms, Nos. 2, 3, and 5, so that should the main sets be temporarily out of action the auxiliary sets could provide current for such lights and power appliances as would be required in the event of emergency.
Electric lighting.—The total number of incandescent lights was 10,000, ranging from 16 to 100 candlepower, the majority being of Tantallum type, except in the cargo spaces and for the portable fittings, where carbon lamps were provided. Special dimming lamps of small amount of light were provided in the first-class rooms.
Electric heating and power and mechanical ventilation.—Altogether 562 electric heaters and 153 electric motors were installed throughout the vessel, including six 50-hundredweight and two 30-hundredweight cranes, four 3-ton cargo winches, and four 15-hundredweight boat winches.
There were also four electric passenger lifts, three forward of the first-class main entrance and one in the second-class forward entrance, each to carry 12 persons.

Wheelhouse on the navigating bridge and the forecastle.
Wheelhouse on the navigating bridge and the lookout station on the crow's nest.
