History

With the D16 and D17 class locomotives becoming life expired, between 1948 and 1952, twelve DD17s were built at North Ipswich Railway Workshops. Per Queensland Railway's classification system they were designated the DD17 class, D representing they were a tank locomotive, and the 17 the cylinder diameter in inches. [1] [2] [3] [4]

The first tank engine was painted black with red lining. The next five tanks were painted blue and the last six engines midway blue. They operated suburban passenger trains in Brisbane out of Mayne depot, mostly on the northside. They also operated freight trains in the off-peaks. [1] [2] [3]

The K class was a branch line steam locomotive that ran on Victorian Railways in Australia from 1922 to 1979. Although its design was entirely conventional and its specifications unremarkable, the K class was in practice a remarkably versatile and dependable locomotive. It went on to outlast every other class of steam locomotive in regular service on the VR, and no fewer than 21 examples of the 53 originally built have survived into preservation.
