The port engine room contained the high pressure ahead ( 240 tons, long with four stage expansion ) and astern turbine ( 120 tons, long ) for the port shaft, the center room contained two low pressure turbines with ahead and astern capability within single casings ( long, nine expansion stages in ahead turbine, four in astern turbine ) for the two center shafts and the starboard room contained the intermediate pressure ahead turbine ( long ) and a high pressure astern turbine ( twin of the port high pressure turbine ) for the starboard shaft.
