Ex SAR Class NGG16 No: 153
ADDED 4th October 2008

In 1907 Herbert William Garratt successfully patented his design for an articulated locomotive we know simply today as a “Garratt”. He died in 1913 at the early age of 49 and left very little in the way of any autobiographical information. He also saw very few locomotives of his design in service.

Although built by a number of manufacturers, it was Beyer Peacock of Manchester that marketed the design most effectively. The Garratt was eminently suitable for all gauges and combined a large powerful locomotive on two short (relatively speaking) wheelbase engine units. Although used throughout the world, it is Africa that is traditionally known as the Garratt Continent. With many railways laid in mountainous areas with tortuous curves, the Garratt design was the perfect locomotive for the conditions.

In South Africa which ran two gauges, the 3’6” Cape Gauge and 2ft narrow gauge, Garratts were to become a common sight on the, then, SAR for over 70 years. The first Garratts for SAR were ordered in 1914 with the Class GA for 3’6” lines and the Class NGG11 for the 2ft narrow gauge. Both locomotives were successes but we shall concentrate on the 2ft narrow gauge and the NGG11 was followed by the NGG13 design in 1927, the NGG12 was also introduced in 1927 but was a small unit for the branches at Upington and Fort Beaufort .

The NGG13 was to become the basis of the standard narrow gauge Garratt for the next 40 years. The class was a great success with its 2-6-2+2-6-2 wheel arrangement and a tractive effort of 18850lbs, making it the most powerful narrow gauge Garratt in the world. In 1937 the design was developed into the Class NGG16 with minor detail differences. Over the next 31 years NGG16’s were built by various manufacturers culminating in the very last batch of Garratts built in the world. The narrow gauge system in South Africa was still very active in 1968 and it was decided to order eight more NGG16. Coincidentally these were also to be the last steam locomotives ordered by the then SAR.

No overseas manufacturer was able to fulfil the order so the eight locos were built at Hunslet-Taylor in Germiston. Although not locomotive manufacturers in their own right, their UK principal, the Hunslet Engine Co., was and supplied the boilers. The locos were numbered 149 to 156 and No: 153 was works number 3898 of 1968.

The entire batch was placed in service at either Port Shepstone or the Donnybrook branch. 153 heading for Umzinto where she worked until her withdrawal in 1987. A mere 21 years in service!

After having her fire dropped at Donnybrook, 153 was abandoned along with hers sisters on the branch but by 1991 she was resurrected together with classmate 113 (also at Sandstone) and put to work on the fledgling Midmar Dam museum project. The demise of this railway and the rest of the museum is well documented as is Sandstone’s rescue project of the locomotives and rolling stock. The rails from Midmar formed the first tracks at Sandstone.

Although 153 was in poor condition on her arrival in 1998, she was given a mechanical upgrade, and has performed faultlessly at Sandstone ever since.

In the early years of the Sandstone rail system, No: 153 was the only large locomotive in service until the introduction of classmate 113 in 2003 and was constantly in demand for photographic days. She also worked at the Great 100 and Great 400 Tractor events hauling hundreds of passengers.

Acknowledged as the “most powerful” of the three working Garratts at Sandstone, number 153 was originally painted green with “Sandstone Steam Railroad” lettering. She is now in SAR black but went through an interim phase with a green boiler and black tanks.

In 2003 No: 153 was part of a triple headed Garratt train that made world headlines. Today 153 is a stalwart of the Sandstone fleet and is set to stay that way for years to come. Already she has been at Sandstone for nearly half the time she saw service on the SAR.
