De Aar, part 2c, Locomotive Graveyard: SAR Class GO No 2586

De Aar Steam Locomotive Graveyard.

Actually this locomotive SAR N0 2586 is stored here for SANRASM, but has not been moved due to the excessive cost, it is pretty well stripped by now.. This locomotive was built in 1954 as works number 28719 by Henschel & Sohn.

Class GO 4-8-2+2-8-4 Garratt

These Photos were taken in April/May 2009.



After displacement by diesels, the whole GO lass was moved to De Aar in 1977, where the locomotives spent seven years on the dump, before being written-off abruptly early in 1984. Only No 2575 and the above engine No 2586 have survived.

In 1938 development in locomotive design and power had led to the introduction of the SAR Class GM, which were noted for their exceptional hauling ability on 60-lb rail. They were also the first Garratt on the SAR to employ the use of an auxiliary water tank, therefore getting maximum power from the axle load, without the limitations of the water supplies carried in the front tank.



It is from "Grand Daddy" Class GM which the Classes GMA, GMAM and also Class GO developed.

Our interest here is focused on Class GO. The GO class was introduced in 1954 and 25 of these fine locomotives were built by Henschel & Sohn.



A variant of the Class GMA, the Class GO was suitable for use on branches laid with 45-lb rail, the Class GO differed in having a smaller boiler. The cylinder castings were lined to reduce their diameter to suit the GO's steaming capacity compared to the GMA. Tractive effort was also correspondingly reduced and coal and water capacities lessened to reduce the overall weight. Many other parts are interchangeable with the GMA.



25 were ordered from Henschel in 1954, and after a brief period on the Krugersdorp-Zeerust line, were placed in service on the Pietermaritzburg-Greytown branch, from whence they were sent to the Belfast-Steelpoort line, although in 1972 they had a short and unsuccessful spell on the Umtata branch. Their final allocation was to the Natal north coast lines before being withdrawn from service by 1975.



The Class GO was numbered N0's 2572-2596.



The occurrence of one of these locomotives at De Aar is a bit of a surprise, but this locomotive may at some stage has seen operation on the lighter track branch line towards Upington, but certainly not as far Namibia - the only Garratts on record to do so was Class GCA 2-6-2+2-6-2 locomotive No 2615 & others working from Windhoek between 1928-32. [source: The First 100 Years of State Railways in Namibia - Bravenboer & Rusch - 1997]

In his book TWILIGHT of SOUTH AFRICAN STEAM, published in 1989, AE Durrant wrote about the GO Class:

"These locomotives were in all technical features identical to the GMA/M classes, but had smaller boilers and cylinders, bringing the axle load down to 134 tons, suitable for use over lighter track, on which they were never utilised. The real purpose behind this design was unclear, as they were never used over lines which could not take heavier power. Possibly their originally envisaged use had disappeared between the time of ordering and time of delivery."

"At the opening period (1973) of this book, all GOs were stationed along the North coast of Natal, at Stanger, Empangeni, and Gingindlovu. Here they worked the main line, then in course of electrification, often double-headed with a GMA/M or another GO, this being the only part of the SAR where double GOs were regularly operated. They also worked the line north to Gollel on the Swaziland border, and were the most powerful locomotives used on this line, for which their design features were finally justified shortly before withdrawal. Both the Eshowe and Nkwalini branches saw GOs used to replace the older GE and GEA Garratts, but on the Eshowe line their fire-throwing capabilities when climbing 1 in 30 gradients through sugar cane fields caused the GEAs to be returned until dieselisation of this and the other lines using GOs."

"After displacement by diesels, the whole class was moved to De Aar, where the locomotives spent seven years on the dump, before being written-off abruptly early in 1984. Thus these modern and very effective locomotives spent only 22 years in service, being replaced by expensive diesels, which were so feeble as to need using in multiple where a single GO sufficed, and whose consumption of imported fuel and imported spare parts became increasingly costly."

Preservation and industrial: No GOs were sold to industry; according to John Middleton's 2002 Railways of South Africa locomotive guide, 2 examples of the GO class still exist: This De Aar engine no 2586 (Hen 28719/54), and no 2575 (Hen 28708/54) -- the latter was still steamable in 2002. See 1999 image below:

De Aar, part 2b, Locomotive Graveyard: SAR Class 12A No 2123


SAR Class 12A No 2123

Actually this locomotive is stored here for SANRASM, but has not been moved due to the excessive cost, it is pretty well stripped by now.. This locomotive was built in 1921 as works number 22763 by North British Locomotive Co.

Wheel arrangement 4-8-2

The locomotive on the left is SAR Class 24 No 3652, the engine on the right is SAR Class 12A No 2123


SAR Class 12A 4-8-2 #2123

The Class 12 locomotive was the first South African Railways design. It was designed by Mr D.A. Hendrie, who was the SAR's first Chief Mechanical Engineer. The Class 12 was built by the North British Locomotive Company, and was placed into service between 1912 and 1922.

The original Class 12 was intended for heavy coal traffic on the Germiston-Witbank run, and spent most of their first years on this section before posted to other centres in South Africa.

The Class 12A locomotive, which was introduced in 1919 just after WW I, was a very much improved version of the highly successful Class 12. The valve gear is Walschaerts. The Class 12A was designed primarily to supplement the Class 12's working between Witbank and Germiston. The Class 12A design marked the maximum size permissible at the time for type 4-8-2.


This locomotive is marked number "2123" which belongs to the series of SAR Class 12A engines.

No 2123 was built by North British Locomotive Co.


By 1969 many Class 12A locomotives were still giving good service, and were seen working in many parts of South Africa. Before the Class 15F's took over the De Aar-Noupoort section, the Class 12A's worked there on mixed traffic. There is little doubt that number 2123 also did service on this section.


The locomotive has a Belpaire firebox. The Belpaire firebox is the flat sides and square corners in front of the cab. The Belpaire firebox was invented by Alfred Belpaire of Belgium. It has a greater surface area at the top of the firebox, improving heat transfer and steam production. Its rectangular shape makes attaching the firebox to the boiler more difficult, but this is offset by simpler interior bracing of the firebox.

Many 12A's were reboilered to become Class 12AR - these engines received a different boiler, which did not use the the Belpaire firebox design, making it easy to distinguish between 12A's and 12AR's.


The Class 12A and 12AR were very successful types. Good performance was accompanied by low repair costs, and modifications in design of details since entering service had been negligible.


The old and the new.

The Class 12A was the final, and certainly one of D.A. Hendrie's finest, designs. While the cylinders were increased to improve tractive effort, the boiler was redesigned and included a combustion chamber.

The following notes come from AE Durrant in his 1989 book TWILIGHT OF SOUTH AFRICAN STEAM:

"Although very different in appearance, it is impossible to consider these two classes (12A & 12AR) separately as they differed only in their boiler design, and tended often to be allocated irrespectively of this. All were built as class 12A, and the class 12AR were reboilerings from class 12A. As may be expected from the class number, they were developed from class 12, and were considerably enlarged all round, other than wheel diameter. Apart from sheer enlargement, the Belpaire fireboxes, common to both classes, were extended in the 12A to include a combustion chamber."

"At the front end, the Class 12 cylinders had small steam chests and indirect 'Z' ports, while the Class 12A had much more direct ports and therefore larger steam chests. With these more modern cylinders the sound of a class 12A locomotive, really opened up, was quite impressive."

"The Class 12A un-rebuilt engines were, at the start (1973) of this survey, mostly in the Western Transvaal, divided between Springs and Germiston. One was at De Aar in the Cape Northern, and a few in the Eastern Transvaal at Nelspruit and Waterval Boven. All were used mainly on shunting, but the Springs engines were also used on the same line duties as recorded for class 12R. Quite suddenly in 1977 all the 12A's were concentrated on the Cape Northern where they shunted at De Aar, a few occasionally being moved to Beaconsfield, Kimberley."

In 2009 Reefsteamers in Germiston has a Class 12AR (Class 12A reboilered) N0 1535 "Susan" in steam. This is the last remaining 12AR in existence. Derek's May 2009 note: "Susan is my favourite loco and I am attaching a pic for you if you want to use it. Sadly she is out of action once again, but we are all holding thumbs that she gets better soon, and doesn't end up being laid up permanently (which is a strong possibility)."

De Aar, part 2a, Locomotive Graveyard, SAR Class 24 No 3652

DE AAR Locomotive Graveyard

SAR Class 24 No 3652

This locomotive was built in 1949 as works no 26364 by North British Locomotive Co.

There is much confusion as to the owner of this locomotive.

Some say this locomotive is stored here for Transnet Foundation Heritage Preservation.

The Class 24 is #3652, which was sold to a sawmill owner (apparently they just wanted the boiler...) , many moons ago, but it was never collected, it has then been claimed back by TFHP.

Other reports has it that it was sold to someone from Namibia (South West Africa) in 1984, but the buyer was unable to come up with the funds to move the locomotive. This was a long time ago, and the locomotive is still standing there.


The locomotive on the left is #3652. It has a Vanderbilt cylindrical tender. In 1901, Cornelius Vanderbilt III, whose great-grandfather founded the New York Central Railroad, invented a cylindrical tender which was soon adopted by a number of American railroads with oil-burning locomotives. Compared to rectangular tenders, cylindrical Vanderbilt tenders were stronger, lighter, and held more fuel (water in RSA loco's) in relation to surface area.

The locomotive on the right is SAR Class 12A N0 2123.


Engine number 3652. This number indicates that the loco belongs to the Class 24 - 100 of these were built by North British Locomotive Co. They were numbered 3601-3700.


The Class 24 is also depicted on a 25 June 2010 stamp release by the South African Post Office. (SAPO). This image is published here by kind permission of SAPO.

The Class 24 is a branch-line locomotive introduced in 1948 for operation on track as light as 40 lb, much of which was laid in SWA (now Namibia). As such this they were intended to displace the old Class 6, 7 and 8 (including the plinthed Class 8F #1236 pictured higher up) locomotives still in service there. The tender is of the "Vanderbilt" or "barrel" type with cylindrical water tank and "Buckeye" bogies.


Class 24 engine No. 3652. There appears to be 3 engines in the grave yard - these two standing end-to-end - and in the distance on the left a 3rd loco - this is a SAR Class GO Garratt.

Two Class 24 locomotives are plinthed in South Africa. One is under a roof at Skukuza and the other one is at the Calvinia museum - both are well cared for.
