NGG16A number 155 to use the modified engine units from number 141!

The original NGG16A number 141, modified at the Alfred County Railway (ACR) in 1989 and privately owned by Phil Mortimer and his son Phil, has been in storage at Sandstone since they purchased the locomotive from the ACR after the demise of the railway in 2004. The locomotive has its original engine units modified to the LD Porta principles unlike number 155 where unmodified units from 142 were fitted to the loco for a proposed overhaul of the modified ones. As ACR ran into difficulties this overhaul did not happen and 155 retained the unmodified units until purchased by Sandstone. As is well known 142 was scrapped at Paddock with 155’s engine units in 2017 after repeated attempts by Sandstone to purchase the locomotive from its owners were refused.

Work continues apace at Sandstone on the engine units for 155. The frames have been thoroughly cleaned and painting them in red ochre has begun. The bunker of 155 has now joined the front tank in the cleaning line and ready for its first undercoat. Wheels and axle boxes have been cleaned and refurbished. Our gallery shows the various stages and conditions of some of the components.

David Fletcher who designs live steam models for Accucraft visited us some time ago and we assisted him with pictures for the Decauville model. One of the examples is our own “Bathala”. Our picture gallery shows David Fletcher with the full size “Bathala” and some pictures of the smaller version. You can learn more about the

The magnetic particle inspection is now complete and the wall thickness testing complete. No cracks were detected in the tube plates and all wall thicknesses are well within specs bar the two back corners but these are cleared by the engineer for welding up. All the small tubes are now annealed and are ready for swaging (all 152 of them!). Window patches for the damaged smokebox are being fabricated and the hollow stays, part of the GPCS inlet system, have bored out. This was quite a long job as the original weld had spread making them difficult to remove. As a critical part of the GPCS system this job has to be exact. Our picture gallery shows the firebox end tube plate after all the weld seams have been measured, the small tubes after annealing, forming of the smokebox patches and the secondary air inlets  during machining to remove them.

While work continues on the boiler in Pretoria, Gert Jubileus and his team have been busy at the Sandstone restoration facility. The overhaul of the engine units for number 155 has begun as our picture gallery shows.  The bearings proved to be in great condition and all the components have been stripped from the frames and  thoroughly cleaned. The loco has been out of service since 2000 when its boiler ticket expired at ACR so 20 years of accumulated grime had to be removed.

The front tank which was removed from the loco on arrival at Sandstone in 2002 has been brought up to the workshop for refurbishment. The loco will be turned out in its original red livery when the restoration is complete.

Preparatory work on the boiler of number 155 has begun in Pretoria with the old tubes being removed and the tube plates and boiler internals thoroughly cleaned. We now have the specifications for the Gas Producer Combustion System (GPCS) inlets on each side of the firebox which comprise a hollow boiler stay with a steel insert. At each outer end are “swirler” plates which rotate the air entering the firebox above the fire bed. Amazingly we have located a number of new ones in the Sandston store which must have arrived with 155 so many years ago that they were forgotten! Our picture gallery shows arrival in Pretoria and work on removing the tubes and cleaning the boiler in preparation for the retube.

After many years of debate Sandstone Heritage Trust has put the wheels in motion for the restoration of the modified 2ft narrow gauge Garratt Class NGG16 number 155.

Sandstone Heritage Trust has an ongoing dialogue with this famous narrow gauge railway in Wales. Nominally referred to as 2ft gauge (610mm as in Sandstone’s case) it is in fact 1ft 11 3/4in (603mm). It was the last steam operated portion of British Rail before being privatised in 1989. We were sad to hear of the passing of one of the original owners recently, Peter Rampton. A somewhat controversial character in preservation circles, he built up a massive collection of narrow gauge locomotives and equipment over the years, much of which was never open to the public. In this collection was a South African connection in the form of NGG13 number 60 and two Lawley locomotives, BR27 and BR28, sisters to the two similar locomotives at Sandstone. Both were acquired from Buzi Sugar in Mozambique. The Vale of Rheidol has produced a magnificent newsletter as a trubute to Peter Rampton for you to enjoy. Click here to read.

Garratt Bucher from the Hempstead & Northern Railroad in Hempstead, Texas, has put together an intriguing article on the very interesting story behind the number plates of the SAR NGG13 Garratts. Garratt’s father, Robert L Bucher, owns the railway and paid many visits to South Africa in the sixties and seventies, having a great interest in the 2ft narrow gauge lines, particularly the Estcourt to Weenen branch which closed in 1983. Such was his enthusiasm that he imported one of the last locomotives to run on the line, NGG13 number 50 which is now in working order on the railroad. South African driver, Billy Bester, who drove on the line, became a close friend of Robert and spent a lot of time in the Texas with number 50.

An interesting contention in the article is Sandstone’s NGG13 number 49 may well actually be number 50 and in the USA, number 50 may well be 49! Any views or information on this will be welcome.

After receiving the required paperwork from the RSR, NG10 number 61 has passed its commissioning test at Sandstone. The final documents are now required from the RSR for the locomotive to be placed into service.

Our pictures show number 61 on the Grootdraai section during its trials.
