Engine N°204 was an “experimental” engine in that it contained a number of unusual features. It was originally designed to burn coke in an attempt to reduce smoke nuisance caused by south east Queensland coal in Brisbane suburban tunnels. Coke burning proved unsuccessful and the engine operated burning various mixtures of coal and coke until the idea of coke as a fuel was finally abandoned. It was also the only engine to operate in Queensland with Southern Valve Gear and “Prairie” wheel arrangement. Other notable features were that it one of the first superheated engines and also the first to be fitted with a “wide” firebox. A new boiler was constructed in 1926 with a reduced grate area following the abandonment of coke fuel. The engine was originally fitted with the surplus tender from PB15 N° 411 that was altered to carry coke. This was later changed to a standard “C16” type to increase its potential range. The engine spent its working life in the Brisbane – Ipswich area mainly on coal trains. It was withdrawn from traffic in February 1950 as the post war engine shortage was being overcome and written off the books in September of that year.
