ASG Boiler

Remnant of the Australian Standard Garratts

 

This ASG boiler had been adopted for static use at some stage.

It is stored by the Derwent Valley Railway at their New Norfolk depot, as seen above on 30 April 2003.

The Australian Standard Garratt (ASG) was proposed and designed by the Commonwealth Land Transport Board in 1942 in response to the urgent need for powerful locomotives for the nation’s 3' 6”-gauge railways during World War 2. The design team was supervised by the Western Australian Government Railways (WAGR) Chief Mechanical Engineer Mr. F. Mills - and to the webmaster’s eye, the ASG bears similarity to his contemporary WAGR S-class 4-8-2 locomotives including the distinctive boiler cowling. Sixty-five ASG locomotives were authorised for production with the components assembled at several Australian workshops:

Newport Workshops (Vic) - 16

Islington Workshops (SA) - 12

Clyde Engineering (NSW) - 27

Midland Workshops (WA) - 10

The first ASG locomotives were in steam within 12 months of design starting, reflecting the wartime emergency conditions in which the class was conceived. They were immediately put into service with initial success, providing significant additional motive power for the heavy wartime traffic. However, it seems that aspects of the design were too rushed as flaws became apparent and in time the ASGs became very unpopular with crews. Indeed, the ASG locomotives were subject to strike action and a Royal Commission in WA. Construction ceased in December 1945 with 57 units assembled and most were destined for relatively short working lives.

ASG locomotives found use across Australia's 3' 6" gauge railways, with a number changing ownership for further service after the war years:

·        25 ASG locomotives worked for the Western Australian Government Railways. These received modifications following the 1945 Royal Commission but were replaced by the more modern W and V-class steam locomotives and first-generation diesels, with the last withdrawn in 1957.

·        6 ASG locomotives were acquired from the WAGR by the South Australian Railways as a stopgap on heavy Cockburn (Broken Hill) - Port Pirie ore trains, pending the arrival of the 400-class 4-8-2 + 2-8-4 Beyer-Garratts. These ASGs were condemned in early 1956.

·        23 ASG locomotives worked for a time in Queensland but were quickly withdrawn at the end of World War 2 and spent most of their time on storage sidings while awaiting a buyer. The excellent history of the Queensland Garratt and other articulated locomotives ‘Crimson Giants’ includes a poignant series of photographs showing the Queensland ASG locomotives stored, boarded up and unwanted, at Mayne and Rocklea in the 1946 - 1950 period. Some were later sold to Tasmanian Government Railways, others to the Emu Bay Railway but the balance were scrapped in the 1950s. One was scrapped having never turned a wheel.

·        14 ASG locomotives worked for the Tasmanian Government Railways.

One of the more successful users of the ASG was the privately owned Emu Bay Railway in Tasmania, which purchased a number and made several improvements. Interestingly these ASGs replaced three earlier Beyer Peacock 4-8-2 + 2-8-4 locomotives which had been supplied in 1929. All the Tasmanian Government Railway and Emu Bay Railway ASG locomotives met the scrapper's torch, however an interesting survivor can be found at the Derwent Valley Railway's New Norfolk depot in the form of an ASG boiler which had been adopted for static industrial use.

The Tasmanian Government Railway was in the habit of re-using otherwise redundant components that could be put to good use, including several ASG water tanks which were adopted for stationary use as lineside water supplies. Four such ASG water tanks survive in the care of the Don River Railway.

In Western Australia, an ASG boiler is held at the railway museum at Bassendean, with another displayed at the Yarloop workshops. It seems that the ASG locos may not have found much success on the rails, but their boilers were very useful as stationary steam plant!

Adrian Gunzberg provides a good account of the ASGs in his authorative book ‘A history of WAGR steam locomotives’. In addition, ‘Crimson Giants’ provides the ASG story from the Queensland perspective, together with the more successful Beyer-Peacock 4-8-2 + 2-8-4 locomotives which superseded them (as represented in preservation by 1009).

The only complete ASG survivor is G 33 which operated at the Fyansford Cement Works in Victoria and is being restored to operation at the Bellarine Railway at Queenscliff, Victoria.

For more information about the ASG locomotives, refer to the page for G 33.

G 33 'Albert A Gunsser' on display at the North Williamstown railway museum on 4th December 1994.

It appears to have recently been repainted into the unlined grey livery worn at the Fyansford cement work.

G 33 is now under restoration to operation at the Bellarine Railway, Queenscliff.

This view was kindly contributed by Tony Bartlett.

G 33's numberplate shows the Commonwealth Land Transport Board parentage of the Australian Standard Garratt locomotives.

This scanned photo dates from a period when G 33 was displayed at North Williamstown in Fyansford grey livery.
