60 CM GAUGE ARN JUNG No 3175
A catalogue picture by kind permission of Chris Walker
My professional interest centres around miniature railway equipment but my private interests range over a much wider portfolio of things mechanical. My Jung, is one of them.
My interest in locomotives is not only in miniatures but also narrow gauge. Over the years my son and I have collected various items of rolling stock in 2` and 2` 6" gauges and hoped one day to acquire a locomotive which we could restore to running order. I bought a "Brigadelok" 0-8-0 Henschel but due to her condition and the weight which was close to 12 tons, we felt it too heavy for what we wanted. We hoped one day we might be able to locate something smaller and our patience paid off! One of our contacts made us aware of such an engine tucked away in Scotland, and its owner was approached, and after careful negotiations a deal was agreed, I was now the proud owner of a delightful little engine!
My loco was built in Germany in 1921 and is an "Arn Jung" work number 3175. she is shown in their works list as a type Bn2t, Jung, as with other German builders, had a code for all their locomotives and in this example means B= 0-4-0, n =not superheated, 2=2X cylinders, and t=tank engine. She is a well tank, meaning her water supply is carried in tanks built into her frames. Her cylinders are slide valve and the bore is 168mm ,originally 165mm when new making her 30 HP. Valve gear is Walchaerts and boiler pressure is 12 bar(170 psi) and her weight in working order is about 5 1/2 tons.
She may have been supplied by "Ducroo and Brauns" who were well known builders and suppliers of steam locomotives, in Hollan, although records indicate she was ordered by agents in Berlin. She was shipped out to Argentina where she spent her working life, of which most of it was working in a large wood mill, where wood waste was used to fire her. She was imported into Britain about 5 years ago and was eventually put into dry storage by its previous owner, who intended to restore her. What appealed to us was her overall condition and that she was 99% complete apart from a whistle and pressure gauge. She was brought her back from Scotland by Steve , of Richards Engineering , who regularly moves locomotive and railway equipment around the country. We travelled up with Steve and it was a two day trip, and by Friday late evening she was safely unloaded at her new home.
We will soon be removing her boiler and letting our boiler inspector carry out a survey and report to see what work needs to be carried out to make her steam-worthy again. The wheel sets will be sent off for re-tiring but the rest of her restoration we intend to do ourselves. We would be more than happy to learn of any information about our engine and would also like to acquire a roof mounted whistle with the operating pin in the top. We will show pictures as the project progresses.

Here we see the loco loaded and leaving for the long journey to its new home, some 400 mile away! Note the smoke coming from the chimney, we could not resist setting fire to some old rags to to create some smoke ,just for fun!
A close up of the valve gear which is in exceptional condition, requiring very little work. The wheels however are badly grooved and will probably need to have new tyres.
A nice view showing her well balanced design. Her chimney is believed to be from an O & K but was fitted to her in Argentina. We may replace it with a stove pipe type, which were also fitted.
THE RESTORATION PROJECT
Now we have had an opportunity to access the Jung , we have drawn up a program for the dismantling of the loco. The first job was to remove all the boiler fittings and plate work so as the boiler could be removed from the frames for examination by a boiler inspector. Out of over 100 bolts only a few required oxy cutting equipment to assist their removal.
Dan and I hard at work in the scorching sun carefully numbering, and removing all plate work and fittings.
At last all boiler cladding removed and time for a break.
The boiler removed from its frames with our 2.5 ton fork truck . The next job was to remove the smoke box from the boiler barrel.
The boiler now ready for its examination and report. We have decided to send the boiler out to a specialist and we would do all the remaining work on the loco ourselves.
Once to boiler had been removed we discovered the builders name stamped into the rear axle.
BOILER AT HUNSLET ENGINE COMPANY
After considering many options we decided to send the boiler to Graham Lees Hunslet Engine Company. The boiler was collected about 3 weeks ago were it would have the firebox, tubes and tube plate removed and the barrel and outer firebox wrapper shot blasted so the boilers condition could be assessed. Monday 11th of August we were invited by Graham to view the boiler and discuss the next stage of work. On arrival at Statfold Barn, where Hunslet Engine Company is based, we meet Graham and his boiler smiths and were shown round the works, very impressive!
We were then shown our boiler and we were astonished at the progress that had been made in such a short space of time. Not only had the fire box ,tube plate, tubes, foundation ring and stays been carefully removed , the boiler had been thoroughly examined, but a schedule of work had been drawn up along with a quote for completion of work. The work will be carried out over the next 8 to 10 weeks.
Here we see the boiler having the remaining stays removed.
The barrel has wasted badly outside the tube plate area in the smoke box. The front of the barrel will have a ring fitted to accept the new smoke box which Hunslets will also make, using some of the original parts like the door, hinges and frame brackets.
The state of the fire box is far worse than we all expected. Some in its time in Argentina, the tube plate was cut out a new plate inserted and welded from inside the box !

WANTED
There are a number of items we will need to put the finishing touches to our loco, and a lamp is one of them .Chris was able to find an early picture of the type we are looking for.
