Seventy [[Victorian Railways R class|R class]] 4-6-4 tender locomotives, the only class of this configuration in Australia and built by [[North British Locomotive Company]], were introduced by the [[Victorian Railways]] in 1951 for mainline express passenger operations. However, the introduction in 1952 of the [[Victorian Railways B class (diesel)|B class diesel-electric]] locomotives saw the R class almost immediately being relegated to secondary passenger and freight use, with many being staged at depots around the state. A number were preserved and some of these continued to operate on special excursion trains.<ref>{{cite book|author=Oberg, Leon |title=Locomotives of Australia 1854-2004 |year=2007 |publisher=Rosenberg Publishing |pages=247–248 |isbn=978-1-877058-54-7}}</ref>

With the privatisation of regional passenger operations in Victoria in the mid-1990s, two R class locomotives were brought back into normal revenue service by the [[West Coast Railway (Victoria)|West Coast Railway]], for regularly scheduled mainline passenger trains between [[Southern Cross railway station|Melbourne]] and [[Warrnambool railway station|Warrnambool]]. The locomotives underwent a number of modifications to allow for reliable high speed operation, including dual [[Lempor]] exhausts, oil firing and the addition of a diesel control stand for multiple unit operation. The use of these R class locomotives ceased after the demise of the private operator in 2004.<ref>[http://www.martynbane.co.uk/modernsteam/pg/westcoast/wcrRclasses.htm West Coast Railway Modernised R Class Locomotives R711 & R766]</ref><ref>[http://www.martynbane.co.uk/modernsteam/pg/westcoast/anatomy.htm Anatomy of West Coast Railway's "Super" R Class, Introduced and compiled by Barry Merton]</ref>

;Tank locomotives
The {{nowrap|4-6-4}} tank locomotive configuration was a popular type with the [[Western Australian Government Railways]]. The [[WAGR D Class|D class]] was introduced for suburban passenger service in 1912. Its successors, both also of the 4-6-4T wheel arrangement, were the [[WAGR Dm Class|Dm class]] of 1945 that was rebuilt from older [[WAGR E class|E class]] 4-6-2 tender locomotives, and the [[WAGR Dd Class|Dd class]] of 1946.

The [[New South Wales Government Railways]] [[New South Wales C30 class locomotive|30 Class]] 4-6-4T locomotives were used on [[Sydney]] and [[Newcastle, New South Wales|Newcastle]] suburban passenger train workings from 1903 until the end of steam operations in the 1970s. No. 3046 is preserved at the [[Dorrigo Steam Railway & Museum]]. No. 3013 is stored, dismantled at the [[Canberra Railway Museum]]. 3085 is awaiting restoration at [[Goulburn Roundhouse]]. 3112 operated tour trains for a number of years but is currently out of service in Canberra. 3137 saw regular use in the 1970s and 1980s as part of the [[NSW Rail Museum]] operating fleet, but is out of service and now on static display at Thirlmere.
