G 1		G	4-6-0	Clyde 126 of 1914	Display	National Railway Museum, Port Adelaide	The Commonwealth Railways selected standard gauge for the Trans-Australia Railway linking Port Augusta to Kalgoorlie across the Nullarbor Plain.  For motive power, a pragmatic decision was made to copy proven locomotive designs and accordingly the G-class were repeats of the New South Wales Government Railways (C) 32 class.  G 1 is now the sole survivor of the Commonwealth Railways standard gauge locomotive fleet and is displayed at the National Railway Museum, Port Adelaide.
Commonwealth Railways - Central Australia Railway (SA - NT)

NB 30		NB	0-6-0ST, converted to 0-6-0DM	Vulcan Iron Work 2533 of 1916	Operational (Diesel)	Pichi Richi Railway, Quorn	NB 30 was constructed as one of 4 identical steam locomotives built in 1916 for the Henderson Naval Base in WA.  Two were acquired by the Commonwealth Railways in 1925 to become NB29 & NB30.  NB30 was converted to diesel in 1958 and is now preserved at the Pichi Richi Railway.
NM 25		NM	4-8-0	Thompson Foundry 51 of 1925	Operational	Pichi Richi Railway, Quorn	The 22 members of the Commonwealth Railways NM class were built to the design of the Queensland Railways C17 class, following the CR philosophy of copying proven Australian locomotive designs.   NM25 survived into preservation following its use as a stationary boiler at Port Augusta until 1975.  In 2003 it was rebuilt and returned to operation by the Pichi Pichi Railway to provide authentic motive power for their "Old Ghan" tourist train through the Pichi Richi Pass.
NM 34		NM	4-8-0	Thompson Foundry 58 of 1927	Display	National Railway Museum, Port Adelaide	NM34 was statically displayed outdoors for many years at the ARHS Mile End Railway Museum.  It was later transferred to the newly-established National Railway Museum, Port Adelaide where it is now proudly displayed with other Commonwealth Railways exhibits.
NJAB 1		NJAB	2-2-0WT	Kitson 4356 of 1906	Operational	Pichi Richi Railway, Quorn	NJAB 1 is a steam motor coach and is affectionately known as the "Coffee Pot".  It is one of Australia's most notable preserved steam railway machines, representing an early type of self-propelled railcar.  NJAB1 Coffee Pot worked out of Quorn depot from 1906 to its retirement in 1932.  It was plinthed at Alice Springs station until transferred to the Pichi Richi Railway in 1975 and restored to operation.
Commonwealth Railways - North Australia Railway (Northern Territory)
3' 6" Gauge
1		NA	0-4-0ST	Baldwin 7860 of 1886	Display	Berrimah Passenger Terminal, Darwin	Sandfly was originally a contractor's locomotive used by C & E Millar during construction of the North Australia Railway.  It appears to be a standard Baldwin design of 0-4-0ST locomotive for shunting and construction work.
5		NF	2-6-0	Beyer Peacock 1717 of 1877	Operational	Pine Creek	There is some confusion about the true identity of the NF-class 2-6-0 locomotive preserved at Pine Creek. It carries the builder's plates of NF 2 but some sources list it as actually being NF 5.  After periods of display at a number of Darwin locations, NF 5 moved to the Pine Creek railway station and was restored to operation in late 2001.
6	-	NF	2-6-0	Beyer Peacock 1721 of 1877	Drowned	Darwin Harbour	NF 6 was originally SAR W-Class W 54 prior to transfer to Commonwealth Railways.  It was shunting the Darwin Jetty on 19 February 1942 when caught during a Japanese air raid and blown into the harbour.  Searches have failed to locate the remains of NF 6 so perhaps it was literally 'blown to bits'.
69	-	NFC	Nfc 69 was originally West Australian Government Railways G 53.
88		NFB	2-6-0	James Martin 37 of 1892	Plinthed	Katherine	Formerly SAR Yx 135, this locomotive was transferred to the Commonwealth Railways in 1943 for WW2 duty on the North Australia Railway.  NFB 88 is now displayed at the old railway station at Katherine.
