Queensland C19 class locomotive
class of 26 Australian 4-8-0 locomotives

The Queensland Railways C19 class locomotive was a class of 4-8-0 steam locomotives operated by the Queensland Railways.
History
The C19 class was designed as a superheated version of the C18 class. Per Queensland Railway's classification system they were designated the C19 class, C representing they had four driving axles, and the 19 the cylinder diameter in inches.
The North Ipswich Railway Workshops built 20 between 1922 and 1928. A further six were built by Walkers Limited in 1935. They worked the heavily graded Main, Southern, North Coast and Western lines.
Nº 702 entered traffic in December 1923 and was named Centenary as it was the hundredth engine constructed by North Ipswich Railway Workshops. In April 1927, 699 operated a Royal train carrying the Duchess of York and in December 1934, 700 carried the Duke of Gloucester.
A number of modifications were made over the years. The early engines had a large regulator dome and another smaller one for the safety valves similar to the B17 class.
This brief starts where responsible research should: with the source description of “Queensland C19 class locomotive” as class of 26 Australian 4-8-0 locomotives. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of 26 Australian 4-8-0 locomotives. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 2, 2025. The linked authority identifier is Q7270913. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1922, 1928, 1935 and 1923.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
