The locomotive as delivered to Sandstone Heritage Trust
RARE DECAUVILLE
2FT NARROW GAUGE LOCOMOTIVE RESCUED

After two years of field work and negotiations, a privately owned 2ft narrow gauge Decauville locomotive dating back to pre-1900 has arrived at the Sandstone Heritage Trust from Angola.

This locomotive was located in the derelict remains of a museum that had fallen into disrepair in the early 1970's.

The locomotive appears to have been in the museum since the 1930's and could date back as far as 1880. Research into its exact identity has confirmed it as Decauville No: 302, built in 1899.

This diminutive locomotive, which has all the charisma and style of a well-bred French lady, is a relatively simple restoration project. It is certainly the smallest locomotive in the Sandstone 2ft narrow gauge fleet, weighing a mere 2 tonne.

We believe that this locomotive was last steamed commercially nearly 80 years ago, and as such will be an interesting subject for steam enthusiasts, photographers and archivists from around the world.

The locomotive is resting after its 3,500 kms road trip from Angola to the Eastern Free State.

We would like to express our appreciation to the many Angolans, both private individuals and at official level, who assisted us with the transfer of this locomotive to the Sandstone 2ft narrow gauge collection, which is being expanded to incorporate locomotives of African as well as South African origin.

News of the Decauville locomotive

The identity of the locomotive has been established without doubt as being works no. 302, built in 1899. Lukas Nel has found this number stamped on motion parts and elsewhere on the locomotive, so the information from John Middleton and others has been proved correct, as was expected!

It was a fortunate survivor of a number of locomotives at the Dombe Grande sugar plantation in Angola. Its sister locomotives, one of which was spotted in a Benguela scrapyard in 1974, were an interesting mix of locos by various continental builders but went for scrap. Our Decauville survived because it was a resident of the Museum, although when discovered the roof had collapsed, thus the damage and woebegone appearance. This had the advantage of ensuring that many of the non ferrous parts were not stolen, it being too dangerous to get to them.

The locomotive first went to Charles Viljoen in Pretoria as he was going to carry out the restoration. Charles dismantled the loco into its component parts, some of the plate work virtually fell to pieces, and cleaned up the frames and repaired the chimney, and did a fine job as can be seen from the photos. It was then decided that Charles should concentrate on the Kerr Stuart Wren Class loco Little Bess so the Decauville loco 'kit' was loaded up and taken to Bloemfontein.

Lukas Nel reckons this is the smallest loco he has ever worked on, having been more used to Class 25NCs, 15Fs and the like during his SAR days.

A start has been made on the boiler, as this is the heart of the loco and its condition determines whether restoration proceeds immediately or a new boiler has to be built. The photos show the basic boiler and the stages of removing the tubes.

The boiler was thoroughly cleaned and the tubes removed, and as can be seen the smoke box is more hole than metal and will need to be renewed, and the barrel and firebox will be inspected, thickness tested etc. Surprisingly perhaps a local supplier has boiler tubes of the correct diameter for this tiny unit, and as the length required is only 1 metre, not many 8 metre lengths are required. One wonders how many other pieces of mechanical equipment, built in a country thousands of miles away, more than 100 years ago, by a company that has long ceased to exist, can have spares purchased ex-stock?

There will be regular updates on the restoration progress of this unique little loco.

Bloemfontein workshop report mid February 2005


Lukas Nel and his small team are making good progress with the locomotives at the Bloemfontein workshop. The value of a husband and wife team like Lukas and Anna, who have created a well motivated, trainable group whose capabilities grow by the week and show the value of skills transfer in a way that is a example to all. Lukas has been involved with steam locomotives for the best part of forty years and works to very high standards as well as knowing all the little tricks that make jobs easier while not compromising safety or standards.

As the number of serviceable steam locomotives declines nationally it is worth remembering that most, if not all, last saw the inside of a railway workshop for major work fifteen years ago or more.


They are all now wearing out and overdue for repairs under the previous SAR protocols. Only by securing decent facilities, the skilled manpower, and transferring those skills to the next generation can steam hope to survive into the future. Sandstone Heritage Trust is fortunate indeed to have a man like Lukas Nel heading up our steam locomotive restoration programme, for he is a steam man through and through.

The ex Angola Decauville is now far from the rusty relic it was when it arrived.

The side tanks are nearly complete and the chassis is on rail and just needs the springs plus final assembly. The springs are finished and Lukas will collect them and the boiler mounts next week.

Work continues on the boiler, which is not in such poor condition as feared. This is no doubt due to the fact that it was kept in the Museum for many years, even if the roof did collapse of late, which prevented much of the corrosion suffered by those left to their fate outside. The photographs show it to be in fair condition although as often happens the bottom of the smokebox had rotted away because of water collecting in it, which combined with any ash present forms a corrosive acidic mixture.

Replica works plates are being made using details from a photo from another loco in Angola for a pattern, as well as assistance from contacts in France who have preserved other Decauville locomotives.
The locomotive was originally named BATHALA but there is no trace of a name plate and no photographs survive of it so named. Does anyone have any details of this which may be of assistance in making replica plates, or were names generally painted on the sides of the tanks like many other industrial locomotives?

The “Decauville” portable railway system was widely used in industrial and military applications and a reprint of the January 1905 catalogue is available from
Feld-und Schmalspurbahnen verlag und Buchhandel e-mail: Karl.Paskarb@onlinehome.de

It contains much detail of the equipment and some fascinating illustrations of a time when rail was king.
Similar designs were manufactured by a variety of French and Belgian companies and there is a similar locomotive built by SA des Usines Metallurgiques du Hainaut, Couillet, Belgium plinthed on the platform at Maputo Station.

Work is continuing on the ex Sena Peckett No 14 (P 2161/1957).

The boiler, which was repaired by SGE Services in Pretoria, has been returned to the frames and the boiler inspectors are sorting out the paperwork concerned.

Because the locomotive was stored under cover at Sena for many years, only being pushed out into the open a year or so before being acquired by Sandstone, most of the platework is free of serious corrosion and has needed a good cleaning to get rid of loose paint and surface rust before being painted. Even the inside lower corners of the saddle tank, which are often where corrosion forms as water gathers, are OK.
There’s a lot of work still to do, making good damage sustained in its Sena days and during its movement to Beira, as well as replacing all the non ferrous fittings and manufacturing missing items such as coupling and connecting rods, slidebars etc. There is also the task of straightening the front buffer beam which was bent in a heavy shunt during its industrial service.

Fortunately thanks to our good relationship with the UK’s National Railway Museum in York we have been able to acquire some drawings from amongst those saved when Peckett went into liquidation. Not everything was saved, but we have a good start with those we have acquired.

A happy team member!

The NG 4 has not been forgotten and the boiler is due for inspection soon. A lot of work has been carried out on the side tanks as the old ones had suffered corrosion and lifting damage in pre-Sandstone days and a new cow catcher has been fabricated.

The rare Jung locomotive ‘Gazengo’ has not had any work done on it of late as it looks likely that a new boiler will be required. We have had no success in acquiring drawings for this locomotive which is perhaps unsurprising given that the Jung works received a major visit by Allied bombers in October 1944 with catastrophic results.

However, we have received permission from Jeff Lanham to reproduce a photograph he took in October 1969 of the locomotive at Bomb Jesus sugar mill by when it was out of use. It, and many other historic photographs of Angolan, Mozambican and African Steam (not South African) are contained on two CDs by Rob Dickinson entitled Steam Safari (South) and Steam Safari (North) and available from Rob, who has been very helpful with our loco research.

Decauville boiler passes its hydraulic test

The boiler of our rare 1899 built 3.5 ton Decauville loco has passed its hydraulic test and reassembly of the locomotive can continue. This is a major step forward in the restoration and the first time the boiler has been tested since the 1920s, it being placed in the sugar estate museum in 1930.
It’s a great credit to Lukas Nel and his team that this very elderly locomotive is making such good progress towards a return to service using so many original parts.
