"South African Sentinel restored"

The steam preservation programme at the Sandstone Heritage Trustestate in the Eastern Free State of South Africa continues unabated with the recent completion of S4 Sentinel Waggon No. 9178 and a 1915 Feldbahn locomotive.

The S4 has had its first couple of days of trial steaming at which it ran impeccably, with no further modifications required.
Keith Stevens has restored the S4 from a very poor condition and has made an outstanding job. Such is the level of motivation upon its completion that Sandstone Trust boss Wilfred Mole and a group of friends are planning to steam it down to the Cape and back in 2007 - a journey of nearly 2000 miles.
The ex-Sena Sugar Estates Marromeu No. 2 'Feldbahn' 0-8-0TT locomotive No. 13779 was built by Henschel in 1915. During WW1 the German Military set up a series of field railways (Feldbahn) to serve various military installations and ultimately front-line positions.
After the armistice, numerous examples of these locomotives were sold around the world including at least 13 to Sena Sugar Estates for use on the Marromeu and Luabo systems. DFB 498 became Sena No. 2.

HTN 187 - Work continues on International Harvester Collection

6th March 2007

The Sandstone Heritage Trust's longstanding relationship with the Cape continues. We presently have two interesting International Harvester products under restoration on a farm near Paarl. The project is being supervised by Jannie du Toit who made available the major collection of International Harvester products to Sandstone Estates.

The first project is an International Harvester Pick-Up truck dating back to 1953. It is a Model R110 with an International Harvester silver diamond engine (Straight Six). The truck was found in a scrap yard at Utrecht in Natal and was in fact an International Harvester farm service vehicle, as clearly shown by the decal on the door.

Oom Jannie must be one of the most experienced International Harvester people in the world. He has been a great friend of the Sandstone Heritage Trust for

many years. Thanks guys, you are doing a great job.

The newly refurbished 'bak'. Badly rusted when received but now in good condition.

The second project is a International harvester Trojan Patrol motor
grader based on the Farmall M product. Trojan manufactured a number of grader
variants using tractors from the Farmall range, Nuffield and others.
The Sandstone Heritage Trust actually has two of these, having acquired one from Whitty Boast's estate
in Natal since the restoration of the Trojan Patrol was started. However, a decision has been made to use one of them for regular road maintenance, which is in line with our living preservation philosophy.

been working on the R110, and Jannie du Toit still sprightly and wide awake,

who redid the engine on the R110 and is providing technical input.

HTN 195 - The Sandstone Heritage Trust obtains an 8-ton Grove crane

23rd March 2007

The Sandstone Heritage Trust has acquired a second-hand 18-ton Grove off-road telescopic crane. The continuous process of recovery in which the Trust is involved requires better equipment than we have at present. This machine will make a big contribution to our efforts in this regard.

The disposal of large numbers of Narrow Gauge locomotives and wagons which is presently underway has created huge challenges for us.

HTN 210 - Sentinel S4 receives first post restoration upgrade

23rd May 2007

Charles Viljoen and Henry Dearlove spent the weekend working on our S4 Sentinel. Charles had to make a number of adjustments which were needed to improve the performance. For every kilometre that the S4 travels more and more items which need attention reveal themselves.

The truck is almost at the stage where it can embark on some serious Road Runs. Our pictures tell the story.

Subject: Re: SENTINEL S4

I must congratulate all concerned for the surperb restoration of the Sentinel S4, the vehicle will most certainly do you proud.
I would however just like to pass on some information regarding the S4 from our records. The vehicle originally worked and came from the then Grootfontein Mine near Springs who donated it to the JHMT through the office of the Late James Hall, it then stood at the museum for many years before being placed on loan with the Midmar Museum in Pmb. When Midmar was eventually closed the items belonging to the museum had to be returned which was the case with the S4. After spending another few years at the museum, it was transfered to Sandstone as per your quote.
I will be interested in the progress of your proposed road trip in the near future and would like to keep contact in this regard, perhaps we could follow portion in order to take photographs and document the story.
Wishing you all the best.

Kind regards,

Peter Hall
Head of Institution
James Hall Museum of Transport.

Container side loader

23rd August 2007

One of our crack technical team commissions container lifter. 

In terms of a working relationship with the Statfold Barn Railway in the UK, the Sandstone Heritage Trust will be entering into a number of locomotive exchange programmes whereby locomotives from Statfold will come out to work a season or two in South Africa and vice-versa.

Statfold specifically said that they would send Narrow Gauge locomotives out in containers which would remain their property and could be used to return the locomotives in due course back to the UK. These containers would be specially fitted with additional spares and other items. As such Sandstone had the challenge of loading and offloading containers, which is now solved by the acquisition of a container lifter. This machine, purchased on a tender from Spoornet Cape Town (for less than £1,000), was transported up to Sandstone where it was checked thoroughly by Desmond Clarke and is now in full mechanical working order. A cosmetic restoration will follow.

Although not a preservation project as such it will probably turn out to be the only container lifter of its type in preservation anywhere in the world. 

We actually have very little technical information on this machine so if anybody has any experience of these machines we would like to hear from them.

The details are as follows:

engine 6cyl cummins turbo
type N7C-230
ENG NO 23138556


NO 33929

How do these old trucks find us?

25th October 2007

You would think we ran a soup kitchen or sheltered accommodation for very elderly trucks because they keep turning up on our doorstep. Two recent arrivals include a Leyland Beaver and a Diamond T. We know quite a lot about the history of the Leyland Beaver but not this particular late model Diamond T. 

Is there anyone out there who can give us further information on the history of these venerable old beasts of burden?




Sent: 18 November 2007

I personally have found that it is almost impossible to research vehicles in SA.

Many Leylands of that period and including one that I own were imported from the UK in ckd form and the cabs were built by Bus Bodies in Port Elizabeth . A round tag about the size of a R5.00 coin will be found inside the cab if this is the case.

If you have the chassis number I can identify the year for you. The chassis plate can be found on the near side chassis rail to the rear of the front spring hanger.

It should also give you the engine number which would apply to the engine originally fitted.

Good luck with the restoration.

Your Leyland Beaver was known as a normal control model.

The chassis number indicates that the year of manufacture was 1962.

The chassis on this particular vehicle was also known as a heavy chassis.

From 1956  Leyland offered a lightweight chassis or heavyweight chassis.

In 1962 heavyweight chassis were numbers 620001-624000 and 629000-629760. The lightweight chassis for that year were numbers 624001 - 626986.

In the 60's a number of forward control beavers were known as super beavers and were exported to Australia and New Zealand although the cabs differ from each other as well as from yours. The cab on your Beaver is very similar to that used on the Scammell Highwayman.

The year of manufacture is quite easy to identify for the years 1944 through to 1962 as  the first two numbers of the chassis number identified the year.

From 1963 to 1966 the chassis no. was proceeded by an L and no reference to the year was supplied, from 1967 to 1969 numbers started with 7 8 and 9 respectively presumably relating to the year again.

The Leyland engine fitted to your Beaver was known as a O,680. This appeared to be standard on Super Beavers where as the early Beaver models had the O.600 (9.8litres) engine as standard with the O.680 (11.1litres) as an option. The O indicated oil engine.

From 1960 the Super Beavers were fitted with the power plus P.680 engine.

One reference I have come across states that the O.680 engine was produced in 1951.

I am wondering how accurate this is or if it is a reference as to when Leyland began designing of this engine as the forward control Beaver that I own has the original engine according to the chassis plate and is engine number 13. So something doesn't quite gel.

The P.680 Power plus engine had the same bore & stroke as the old O.680 but the head was redesigned and twin inlet and exhaust manifolds were used to give better gas flow as well as a few other improvements, The result was an increase to 200bhp, 33% more than the O.680 engine.

I hope you find the above information of interest.
