the titanic...
The Titanic was powered by two four cylinder, triple expansion, reciprocating steam engines. Each could deliver 15,000 horsepower at 75 revolutions, producing a speed of 21 knots.
There were also four 400 kilowatt steam-powered generators with dynamos capable of providing enough electricity to work the machinery controlling the winches, cranes, passenger and service lifts, heaters, cookers, water-tight doors, the internal telephone exchange and the Marconi wireless set to a range of 350 miles.
