The Queensland Railways DD17 class locomotive was a class of 4-6-4T steam locomotives operated by the Queensland Railways.
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.
The first was painted black with red lining. The next five were painted blue and the last six 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.
