The Queensland Railways C19 class locomotive was a class of 4-8-0 steam locomotives operated by the Queensland Railways.
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. Those built from 1926 onwards had a boiler with only one small dome that contained both regulator and safety valves. Earlier engines later received this type as they became due for re-boilering. Both the initial and the subsequent boilers shared a firebox having a long, narrow grate which required considerable effort on the part of the fireman, and rendered them unpopular.
