The two middle shafts, capable of reversal, were each driven by a low-pressure turbine, which in emergencies could each be driven by exhaust from the high-pressure turbine. Each shaft drove a four-bladed bronze propeller for a designed sea speed of 19 knots. Steam was provided by six double-ended and four single-ended forced draft boilers divided between two boiler rooms. On trials in the Firth of Clyde ''Calgarian'' attained and on a double run for contract speed made , above required service speed.
