Sulzer Brothers
History & Production Details
For Rail Traction

This page last updated June 10th 2008 - updates for the Faur built 6LDA28 powered locomotives.

For what its worth this is my attempt at trying to produce a list, by country, of diesel locomotives and railcars powered by Sulzer engines. These engines were built over a period of at least sixty years and powered trains all over the world. Some have been well documented and examples have reached preservation whilst other worked out their years in the less well travelled parts of the world, then disappeared into oblivion.

The list is compiled from many sources of information. An illustrated booklet produced by Sulzer Brothers in 1967 featuring their traction engine production from 1911 - 1967 was most useful. Information from that booklet and other sources is incorporated in these pages. Without a doubt there are many minor 'errors' on this page, which may simply be variances in records relating to, for instance, ordering dates versus delivery dates or modification of factory rated horsepower to local ratings dictated by altitude or high temperature climates.

Large orders for power units frequently included spare engines as part of the contract.

For many of the entries further detailed information can be found on a particular country's Sulzer powered locomotives by clicking on the link at the bottom of each country table.

Notes
(1) This engine has absolutely nothing to do with Sulzer engine development for rail traction. It is included here simply because it carried the Busch/Sulzer name, all development was from Busch.

In general the larger Sulzer engines did not meet the expectations of the North American market with the AT&SF & UP quick to sideline these locomotives as problems began to occur.

The following is a narrative describing (hopefully) the roots of the Sulzer engines in the UK that led to the introduction of the Class 24.


An advertisement from 1963 depicting the Brush Type 4, powered by the Sulzer 12LDA28C engine.

The firm of Sulzer Brothers was founded in 1834 comprised of the father, Johann Jakob Sulzer-Neuffert and his two sons, Johann Jakob & Salomon. The building of a foundry in Winterthur, also in 1834 led to the beginnings of the production of numerous items including iron castings, heating radiators, steam boilers and stationary steam engines. Expansion took place into pumps, fans, paddle steamers and refridgeration equipment. The production of ice making machines for Professor Carle von Linde brought the firm into contact with Rudolf Diesel, a student under Professor Linde. Diesel had arrived at Winterthur in 1879 under the recommendation of Linde, to gain some practical engineering experience whilst waiting to re-sit his exams, missed in 1879 due to a bout of typhoid fever.

In February 1892 Diesel applied for his famous Patent that heralded the birth of the diesel engine, although at this time it was little more than ideas & hypotheses. Initially he received little support for development of his patent, in widening his search for interested parties he forwarded a copy of his book to Sulzer Brothers, also personally corresponding with their chief engineer, Wilhem Zublin. The response from Sulzer was lukewarm, even Sulzer's prinicipal advocate Johann Jakob Sulzer-Imhoof remained interested but cautious. They, like many others were interested in the scientific aspects but seemed wary of the commercial prospects for this new technology. However an agreement was signed in May 1893 with Diesel to allow Sulzer Brothers exclusive rights of Diesel's patents in Switzerland and to receive all discoveries from the research carried out by Diesel at Augsburg. Sulzer Brothers were one of ten licensees signed to Diesel's patents. Diesel's initial machine was completed in July 1893, but took a further seven months to reach an acceptable level of operation. J.J. Sulzer-Imhoof visited Augsburg several times, in November 1895 to see Diesel's original engine and then in February 1897 to witness successful demonstrations of a second engine. The thermal efficiency of this engine was greater than double that of current steam engines, a fact which led to Sulzer (and many of the other licencees) to build and test its own diesel engines. This resulted in the succesful running of their first engine during June 1898, a single cylinder four stroke engine developing 20bhp.

In 1898 a holding company, the Allgemeine Gesellschaft fur Dieselmotoren AG was established to handle all rights to Diesel's patents. All licencees provided the holding company with data obtained from research into this new technology. Many pitfalls were encountered and Sulzer Brothers were also encumbered with the 1893 agreement that seriously limited the markets open to them. A new, broader licensing agreement drawn up in 1903 provided them with the impetus to create a diesel engine department, a research area for the two & four stroke designs and a sales department. Winterthur's first order came in January 1903 for twelve 35hp single cylinder engines. The journey had begun. By 1906 twelve engine sizes were available, with outputs from 15 to 600 bhp.

Although the commercial success of the diesel engine was now assured, its chief creater, Rudolf Diesel suffered a series of financial set backs as well as falling into poor health. On September 29th 1913 Diesel and two colleagues boarded a steamer bound from Antwerp to Harwich. He was not seen alive again, a body carrying his identification was later found by a Dutch vessel, and in line with tradition at the time the remains were buried at sea.

Sulzer's use of worldwide licencees to build their engines was a remarkable pioneering business decision which over time proved to be the correct one considering the location of Winterthur. The first licencee in the UK was William Denny & Brothers of Dumbarton in February 1913, followed by Sir W G Armstrong Whitworth Co Ltd, Newcastle upon Tyne in March 1920.

The initial direction of Sulzer's new found diesel engine production was for stationary applications, the 'D' & 'K' models. However the fitting of the French canal barge 'Petit Pierre' late in 1903 with AB Diesels Motorer 25hp diesel engine saw the first successful marine application. Sulzer's first application 'at sea' was in a Leeds - Liverpool canal boat in 1905 with a two cylinder thirty horsepower 'D' series engine. The application was not a success, but as usual the experience was priceless. And so it would be through to the end of the 20th Century, when their 12RTA96C, at the time the world's most powerful diesel, and delivering just under 90,000hp entered service in some P&O vessels.

For the railway application Sulzer built rail traction engines between 1912 & 1992. Their first attempt, like the English canal boat was not a success. The 1912 built 'Thermo-Lokomotive' containing a four cylinder two stroke 1,000hp diesel engine (a 4LV38) was a failure, the unusual starting procedure and the direct transmission proving to be major weakness in the design. Two years later five railcars for the Prussian & Saxony railways proved to be the better starting point for rail traction, fitted with faster running four stroke engines (6LV26's) and coupled to an electric transmission.

In the United Kingdom the firm of Armstrong Whitworth of Scotswood, Newcastle established a diesel traction department in 1930/31, employing use of the Sulzer line of engines. Three Sulzer powered 250bhp LNER railcars were manufactured in 1932 for the Tyneside area. In 1934, the LMS ordered a diesel electric shunting locomotive (7408, later 7058) powered by a six cylinder Sulzer engine (6LV22), with electrical components from Lawrence Scott and Electromotors of Norwich. This was based on an earlier 1932 built machine destined for industrial service and which would outlive the LMS shunter. It trialled at Willesden and Crewe, and clearly showed its superiority over the diesel mechanical types. The advent of WW2 saw it borrowed by the War Department between 1941 - 1943, returning afterwards to Willesden. Its final years were spent at Toton, being allocated BR number 13000, but never carried as its service ended in November 1949, being scrapped two months later at Derby Works.

By 1935 an order for twenty shunters, based loosely on 7058 and 7079 (the E.E. variant) was issued by the LMS. Ten were delivered by Armstrong Whitworth late in 1936, numbered 7059 - 7068, using the same Sulzer engine as 7058, a 6LTD22 model, now rated at 400hp. This increase was achieved by lightening the components and increasing the rpm from 775 to 875. The main generator and traction motor being supplied by Crompton Parkinson. The jackshaft drive was continued over from 7058, but the main fuel tank was now placed between the cab and the engine compartment. All entered service in 1936 split between Crewe South and Kingmoor. Starting in 1940 they were all requisitioned by the War Department, seeing service in France, Belgium, Holland and Egypt. Four were eventually purchased by the Belgian Railways, the last not being retired until January 1966. Two were sold to the Egyptian State Railways in the early 1950's, remaining in service until 1974. Two suffered mechanical problems and saw no service after the war's end whilst the remaining two saw much use by the War Department in the UK before being sold to private buyers. Prior to World War Two Armstrong Whitworth closed down its diesel traction department.

The 'LD' series of engines came into production in 1933 with Armstrong Whitworth's prototype 'UL' locomotive in the UK and other pioneering locomotives built in France. Gradually the 'LD' series would become Sulzer's primary offering for traction needs. During the 1930's thirty countries operated Sulzer powered rail vehicles whilst by 1937 a single engine producing in excess of 2,000hp was available. This culminated in the twin bank 12LDA31 from 1937/38, used in double locomotives built for use in France & Roumania. The nomenclature of the engine designations was, for example, 6=cylinders, L=traction i.e. locomotive, D= direct injection, A=blown/turbo charged (from the German 'Abgasturbine'), 28=cylinder bore in centimeters.

The 'LD' series engines first appeared in the British Isles in mainline Sulzer powered locomotives built in 1951 at Inchicore for the CIE. They were 80ton Bo-Bo's of 915hp (later 960hp), numbered 1100/1 powered by a 6LDA28 engine at 750rpm, with Metropolitan Vickers electrical equipment. During 1954/55 BRCW, Sulzer and Crompton Parkinson produced twenty machines for Commonwealth Railways (14) and the Sierra Leone Development Corp. (6), using the 6LDA28 of 900/1000hp. During 1956/7 the CIE ordered 12 A1A A1A machines, again Metropolitan Vickers supplied the electrical equipment, but assembly was by BRCW. With this last order however the diesel engines were constructed at Vickers Armstrong's plant at Barrow in Furness, rather than at Sulzer's Winterthur plant. By the time of the first BR/Sulzer Type 2 order Sulzer were firmly established with a product that could be bought 'of the shelf'. With a British Transport Commission requirement mandating orders to go to English firms, the Sulzer engines were built under license by Vickers Armstrong at Barrow, who at that time were enlarging their workshops to handle a production run of about 1,450 power units. During the height of production 12 - 15 engines were turned out each month. This number included about sixty spare power plants. To allow Vickers Armstrong time to tool up Sulzer supplied the first ten 6LDA28A engines from their plant at Winterthur.
