These versatile engines were a superheated version of the C16 Class. This class contained more engines and was constructed over a longer period than any other type on QR. In fact, some earlier members of the class had been withdrawn before the final ones entered service. Commonwealth Railways NM Class was based on this design. They were used to haul Mail Trains on lines that could not accommodate heavier (B18¼) engines, also suburban passenger, mixed, goods and branch line trains. Until 1948 they were the heaviest engines that could work north of Mackay. Prior to the introduction of 60ton DELs, they were responsible for hauling the air conditioned Inlander, Midlander andWestlander trains for parts of their respective journeys.
First engines had large steam domes, open cabs and C16 style tenders. Those built from 1938 onwards, commencing with N°858, had small steam domes, sedan cabs with welded tenders, larger diameter (9½”) piston valves and also Laird crossheads in place of the Alligator type fitted to earlier engines. The two types of boilers were occasionally interchanged at overhauls and by later years the majority of the old style ones had been replaced. Most of the earlier engines were eventually fitted with the larger 9½” piston valves.
The last 40 engines, N°961 to N°1000, were fitted with roller bearings and painted brown with green trim. They acquired the nick name of “Brown Bombers”. Those overhauled in the last years of steam operations were repainted black. Some other members of the class were also painted brown briefly after overhaul but it was soon emphasised that that colour scheme was only to be used on roller bearing engines. A number of modifications were carried out over their life, the most noticeable probably being the fitting of large mushroom air snifting valves. Several had additional sandboxes and/or rear headlights fitted at various times for working lines where no turning facilities were available.
We identify rebuilt and renumbered locomotives from this class as well as other classes with similar mechanical configurations and present those classes below.

|New description||Following on from the failed attempt to superheat the proven C16 Class design, QR was quick to amend and improve the design to the point that it became a new class in its own right, the C17 Class. Many features of the C16 Class transferred across to the initial batch of C17's, such as the larger steam dome, open cabs and tender design. Class members built after 1938 received smaller steam domes, sedan cab, welded tender, larger diameter piston valves and 'Laird' type crosshead replacing the 'Alligator' type used on older engines. The final batch of C17's (N°961 to N°1000) also received roller bearings and a distinctive chocolate brown livery. C17 Class locomotives proved themselves true 'maids of all work', handling goods and passenger workings with ease. Prior to the introduction of diesel traction C17's where responsible for hauling "The Inlander", "The Midlander" and "The Westlander" air conditioned trains. Such was the success of the C17 class, they became the most numerous locomotive type employed by QR. With Commonwealth Railway's also adopting the design with only minor modification for its NM Class locomotives.|
