She was propelled by three Yarrow type water tube boilers powering Parsons geared steam turbines developing 27,000 SHP driving two screws for a maximum designed speed of 34 knots.
The original equipment included a horse wagon, chief's buggy, and a pumper that used a vertical tube boiler.
However, during the voyage, her tube boilers began to leak profusely, and she had to be repaired in Colombo Ceylon by a repair team sent from France.
The steam was supplied by six cylindrical tube boilers with a maximum working pressure of 413.6 kPa (60 psi).
The importance of ductility was recognized by some very early in the development of tube boilers, such as Thurston's comment:
Hence the name, and considerably reduced diameter, compared to the ubiquituous Scotch or return tube boiler.
Parallel tube boilers place all of their fire-tubes in a single parallel group, running from side to side of the boiler shell.
Radial horizontal tube boilers avoid the flat tubeplate of the Cochran boiler in favour of a circular firebox, a shape that better resists pressure.
LMS 6399 Fury, built in 1929, was an unsuccessful experimental prototype locomotive with a high-pressure, water tube boiler and compound 3-cylinder drive, based on the Royal Scot.
This boiler is internally fired and water tube boiler.
