Stafford manufacturing history

 A power house of British electrical engineering, Stafford was of course a shire town but one that was soon outgrown by other towns in its county. One reason was that the man road route following the course of the Trent by-passed it. When the canals came they too passed it by until a passage was created by dredging the river Sow and adding an canalised section.



The tradespeople of Stafford carried on the common trades, but slowly a larger group emerged whose business was making shoes. The wearing of shoes had become more common in London, the growing industrial towns and the colonies and so a strengthening demand developed for Stafford's shoe makers. In his book Stafford Past, Roy Lewis suggests that one name drew ahead of the field, that of William Horton. In many ways like Manchester cotton merchants, he had a network of outworkers for whom his workshop would cut the leather for soles and uppers and the outworkers would stitch them and return them to him for payment and the next batch of leather. At one time he is said to have had one thousand outworkers. Finished shoes would be despatched by canal to the growing urban areas. The Napoleonic wars boosted demand but then competition from the lower paid Northampton shoe makers attracted trade away.

Railways did not pass Stafford by, rather the town became something of a hub for Staffordshire's part in the growing rail network. Workshops were set up and successive stations built. More significantly the town embraced massive marshalling yards where wagons arrived and were despatched right around the country. Not surprisingly locomotive manufacture took hold and W.G. Bagnall emerged as a leader.

As with the other shoe towns, the advent of American sewing machines for shoes led first to strikes as men refused to work on machine stitched leather. In time, as elsewhere, machines became a fixture along with factory production. Stafford's factories found themselves specialising in women's shoes and the firm Lotus became the best known of Stafford's factories. As elsewhere, foreign competition shrank the workforce to one or two specialised factories.

Supporting the shoe making trade, there emerged a cohort of manufacturers of the equipment needed to make shoes but also the packaging, laces and polish the wearer would need. The British United Shoe Machinery Company was set up by its American counterpart and took over the shoe related business of W.H. Dorman. This company would move into motor vehicles with the Redbridge Motor Works and aero engines with Adams. In the First World War they developed the interrupter gear that enabled machines guns to fire between the blades of a spinning propeller. After the war, the company built its first diesel engines. In 1959 it acquired W.G Bagnall and two years later became part of the English Electric. Later still it would join with Perkins diesels of Peterborough.

At the start of the twentieth century, Stafford attracted the British Siemens Brithers whose premises at Woolwich were becoming too small to house both its cable manufacture and its business of dynamos and electric motors. It was these latter two which Siemens moved to Stafford. Siemens Dynamo works later joined the group of companies which in 1919 formed English Electric. I write of this in How Britain Shaped the Manufacturing World.

Roy Lewis writes of the arrival in 1930 of George Nelson as managing director of English Electric and how he encouraged its growth in a very hands on way, his home being through a garden gate in the factory fencing. The Second World War saw the factory produce tanks, bombs and a range of electrical equipment. In 1960 the company opened a new transformer factory and in 1968 merged with GEC. I write of this in Vehicles to Vaccines. In 2015 the Stafford Grid and Power businesses became part of the American General Electric, now GE Vernova, which is working on high voltage transmission for the transition to net zero.

Stafford was also home to British Reinforced Concrete Engineering Company and in the Stafford Salt and Alkali Company.

Swindon manufacturing history

Swindon would become one of the great 19th century railway towns, but at the end of the 18th century it was a place largely passed by.

Kennett and Avon canal 

The canals changed this as the ambitious link between the Thames and the Avon was debated. What became the Kennet and Avon canal was the southern link through the Vale of Pewsey. A northern route branched north near Melksham and made its way between Calne and Chippenham to pass close to Swindon on its way up to Abingdon on the Thames. Later. the north Wiltshire canal would link from Swindon to the Thames and Severn canal at Cirencester.

From next to nothing, Swindon had become an ‘epicentre’, well nearly. The impact though was real with a big drop in the price of coal from the Somerset coal fields and access to hungry urban areas for the agricultural produce of north Wiltshire farmers.

No sooner was all of this in place than Isambard Kingdom Brunel was appointed chief engineer of the yet to be built Great Western Railway. Debate followed but the route adopted would pass through Swindon after Didcot and before Chippenham and the Box tunnel through to Bath and Bristol. A little later a line would snake north west from Swindon through to Cheltenham.

A few lines of text belie the task. 1840 was in the middle of one of the 19th century’s downward economic cycles. Many railways were being built, but they were mostly short runs linking towns and neighbouring coalfields. The longer routes (The Grand Junction and the London Birmingham) were massive undertakings involving great financial risk. The GWR was no different, especially with the cost and complexity of the Box tunnel. Nevertheless it was built and opened to traffic.

The new line would need a repair workshop. John Chandler, in his Swindon - History and Guide, tells the story. Swindon was simply not suitable: it had an inadequate water supply and really no skilled labour. Surely Bristol would be better, closer to coal and with an already large population. Daniel Gooch had been appointed to create the workshops and he argued for Swindon. There were those who suggested that local landowners may have sought to influence him. Other factors also came into play. Land was available at Swindon by merging with Cheltenham railway. Swindon was also at that point along the route where a change of engine would be needed to take on the challenge of the route through the Box tunnel.

There was still no money until the idea emerged of a station at Swindon offering refreshment to passengers as the engines were changed. This resulted in grand three storey station buildings constructed along with a village of railway houses all at the builder’s expense in return for the profits from the station. Anecdotes suggest that the quality of refreshment was not great and that prices were on the steep side - perhaps nothing changes.

The building of the workshops began during the economic downturn, but by the time of the railway mania that followed, locomotives were not only being repaired but new ones were being built. The GWR had opted for a broad gauge railway in contrast to the narrow gauge adopted elsewhere. This had the advantage that locomotives could be bigger and more powerful - in 1846 a locomotive, the Great Western, could pull a full passenger train at 60 mph over a long distance. The emphasis on power and speed is born out by the contrasting comments on the Crewe works.

In terms of employee numbers, Chandler quotes 400 for 1843 growing to 1800 by 1847, but then shrinking back to 600. Towards the end of the century, tough economic conditions gave way to better times and employee numbers climbed to 11,500. Alongside a better economy, the GWR had diversified and expanded its routes. Crucially it had moved over to the new standard gauge in 1892. Possibly more important it had added a large carriage works in 1865 and was producing rolling stock built to the highest standards of luxury. Magnificent locomotives were built including the legendary Castles, Kings, Granges, Manors and Halls classes. The works expanded in area eventually covering 326 acres including 79 acres roofed over. Even in 1846 the engine shop could accommodate 36 locomotives in a building in the shape of a stable with separate stalls.

Swindon was ever more dependent on the railway with some 80% of adults males employed there. Clothing factories were attracted by the corresponding availability of female labour: Compton employed 1,000 including the manufacture of GWR uniforms.

Employment at the GWR works grew to 14,369 in 1925 but then begun its decline to 10,000 until 1960, 5000 in 1967 and just over 1,000 before it closed in 1986. I write about the massive changes in the post war railways in Vehicles to Vaccines.

Swindon attracted other industries. It became home to a Pressed Steel factory which continues to supply bodies for the Mini. The Vickers site in Swindon first produced Spitfires in the Second World War and then was used for experimental projects. The site was then taken by Honda for their UK production base. It is currently being redeveloped once more. Plessey opened a factory in Swindon during the Second World War to meet demand from the MOD. The company also managed a number of shadow factories. The Swindon factory later specialised in hydraulics and a further factory was built at Cheney Manor in 1957 to manufacture transistors. RA Lister built a factory to manufacture farm equipment and diesel engines to add capacity to its main base at Dursley.

A town created by the railways - Crewe

 Crewe is the third town cited by Asa Briggs as created in the 19th century. It was created by the railways for the railways and Diane Drummond, in her book Crewe: Railway Town , Company and People 1840-1914, offers a precise date, 10 March 1843, when the first employees and their families were settled there.

It later became home to Rolls-Royce Motors. The image is of General Montgomery's Rolls-Royce probably manufactured in Derby (see below).

It was the Grand Junction Railway that decided Crewe was the place for its main works. It had become the place where a number of separate railway lines met what would become the west coast mainline and so it was a logical location for the factory that would maintain and manufacture locomotives and rolling stock but also rails.

Drummond offers a glimpse of the scale of railway manufacture by comparing Crewe with Swindon which was home to the works of the Great Western Railway. Crewe's initial workforce in 1843 numbered 1,150 compared to Swindon's 423. However by 1847 as a result of economic downturn, Crewe's workforce had reduced to 1,000 whereas Swindon's had increased to 1,800. Looking further ahead to 1900, Crewe employed 7,500 and Swindon 11,500.

Crewe might not have been the biggest, but it laid claim to be the most technologically advanced. Drummond suggests that, having a single customer, the works followed a path of vertical integration. At one time it made everything used in locomotive manufacture except copper piping. Famously it built its own iron and steel works being one of the first to embrace the Bessemer and then the Siemens-Martin processes. Carr and Taplin, in their History of the British Steel Industry, tell how the Chief Mechanical Engineer, John Ramsbottom was persuaded by William Siemens to instal open hearth furnaces for the conversion of old iron into new steel rails. In addition to furnaces, Ramsbotton installed a new rail-rolling mill to be added to ten years later by a second mill with an updated design by the next Chief Mechanical Engineer, Francis Webb. These two respected engineers followed in the footsteps of Francis Trevethick, son of Richard Trevethick, who set up the Crewe works.

It was said that Crewe built locomotives for economy, leaving GWR to win plaudits for power and speed. Nevertheless, Crewe earned respect for their training of young engineers among whom was Nigel Gresley. From the start, Crewe operated a division of labour with as many as nineteen different trades including: 'smiths and their strikers; moulders and their assistant dressers and casters; pattern makers and coppersmiths; boilermaking trades of platers, riveters and 'holders-up'; turners; coachbuilders and engine fitters'. Basic machine tools were employed such as lathes, 'slotting, shaping and planing machines'. Under Ramsbottom new machine tools were introduced in the 1860s and 1870s resulting in increasing standardisation using interchangeable parts. In this Crewe was perhaps twenty years ahead of the so called Machine Tool Revolution which transformed other engineering companies in the 1890s. One consequence of the increase in mechanisation was a change in the composition of the workforce with a higher proportion of general labourers and fewer skilled men.

Drummond takes her reader through the essential elements of the process of constructing a railway locomotive which I simplify in the interests of highlighting the growing role of machine tools. The starting point is the foundry where the iron is made which can then be cast, or puddled to become more malleable wrought iron. The invention of steel eventually took the place of wrought iron. In the railway workshop, parts would first be moulded, that is a mould would be created and the molten metal introduced. Moulds varied massively in complexity and so the skill required in their making. Should parts need to be joined, this was then undertaken by the smithy. Welding, as we know it, came very much later. A locomotive could comprise some 5,000 parts each of which would require a degree of finishing using perhaps a lathe. This was the job of the turner. As time progressed the number of machine tools increased and so a larger proportion of the work was carried out by semi-skilled machinists. For a locomotive, the construction of the boiler was central. Again, this was a combination of skill, machine power and stamina - it was hard work. The final part of the process was down to teams of fitter-erectors who would put all the parts together; this was one of the last stages of the process to employ machine tools. (I can't help having in my minds eye, as a contrast, the robots on the production line at today's Derby works)

This was surely a complex process and one that had to be married with work in repairing locomotives. The whole was carried out in a cyclical economy presenting management with massive challenges in balancing the books. At Crewe a device of compulsory unpaid holiday was used to match the workforce with the hours needed for the work. This unsatisfactory arrangement was eventually superseded by lay-offs, inevitably met with resistance.

All this happened in a town where employment in the railway works was life for a large proportion of the population. Towns with a wider spread of employment were far less vulnerable to the foibles of the economy.

For Crewe, the years immediately preceding the Second World War brought Rolls-Royce and a factory to manufacture aero engines. (The image is of General Montgomery's Rolls-Royce probably made in the Derby factory.) After the war the factory took over the manufacture of both Rolls-Royce and Bentley motor cars, with the Derby factory giving its focus to jet aero engines. As I tell in Vehicles to Vaccines, Rolls-Royce Motors split off from the aero-engine company and continued manufacturing in Crewe. At the turn of the twentieth century the German BMW bought Rolls-Royce and built a new factory at Goodwood in Sussex, VW took the Bentley brand and upgraded the Crewe factory. Both companies continue to trade successfully under their new ownership. Bentley is now the largest private sector employer in Crewe.

Derby and the Museum of Making

 The city of Derby is a home of British engineering and of probably the first textile factory at the Silk Mill. This has been repurposed to tell Derby’s story. The image is of the mill with thanks to the museum.

The Museum of Making takes the visitor through the astonishing array of manufacturing activity carried on in this midlands city really from the eighteenth century onwards. The museum has one floor titled simply assemblage and they suggest that this looks more like a museum store than a curated display. These photographs help to give a flavour

Voltage regulator

The entrance picks up one of the earliest contributions in the Silk Mill itself, an early example of the factory manufacturing system, taken further fifty years later by Arkwright at Cromford Mill

A work in progress paying homage to the Midland Railway

The railways are the subject of many exhibits from rails, signals to telegraph equipment, but no locomotives (you need to go to York for them). There are mock ups from the Derby railway workshops, not least the Intercity 125. It is clear that the Midland Railway based in Derby was a leader.

You can just about see a wooden mock up

Lawnmowers tell of the presence in the city of Qualcast. Fashion wear speaks of the ground breaking work in artificial fibres at British Celanese later part of Courtaulds. There are a number of eletrical equipment manufacturers. Ceramics feature with industrial examples on display; Crown Derby and Denby will be found elsewhere.

There is a Rolls-Royce aero engine suspended from the roof and information boards telling the story of this, the city's most illustrious son which came to its site at Sinfin Lane because the local authority could offer electric lighting. There are on display models of Hawk and other famous engines.

Derby did its job in war time in addition to Rolls-Royce Merlins, there was a huge army Motor Transport depot
